Replaceable Light Source Information; Federal Motor Vehicle

Safety Standards Lamps, Reflective Devices, and Associated Equipment

AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This document amends the Federal motor vehicle safety standard

on lighting to allow high intensity discharge (HID) light sources to be

used in replaceable bulb headlamp systems, in addition to their

presently allowed use in integral beam headlamp systems. Adoption of

this amendment requires corresponding amendments to part 564, the

regulation under which Docket No. 93-11 was established as a depository

for replaceable light source information. However, if the life of the

light source approaches that of the vehicle, as is the case with HIDs,

interchangeability will no longer be so important. Therefore, NHTSA is

adding Appendix B to part 564 which allows a manufacturer to submit

fewer items of dimensional information if it can demonstrate that the

rated laboratory life of its light source is not less than 2,000 hours.

DATES: Effective Date: The amendments to the Code of Federal

Regulations, and the requirements of the amendments, are effective June

6, 1996.

Petition Date: Petitions for reconsideration must be received not

later than June 21, 1996.

FOR FURTHER INFORMATION CONTACT: Kenneth O. Hardie, Office of

Rulemaking (202-366-6987).

SUPPLEMENTARY INFORMATION: On June 19, 1995, NHTSA published a notice

in the Federal Register to initiate rulemaking that would amend

Standard No. 108 so as to allow replaceable bulb headlamps to

incorporate short arc discharge light sources (60 FR 31939).

As NHTSA noted in the NPRM, short arc discharge headlamp systems

are commonly referred to as ``high intensity discharge'' (HID) systems.

Presently, the only HID application in production for lamps covered by

Standard No. 108 is in headlamps, and the only way HID headlamps can be

used under Standard No. 108 is in an ``integral beam headlighting

system'' (Section S7.4). Thus, today, HID headlamps are comprised of a

headlamp body (including reflector and lens), a small transparent

envelope containing a specific mixture of gases under high pressure

(the discharge bulb), and an electronic ballast to convert low voltage

direct current to a controlled output high voltage direct or

alternating current to drive the discharge bulb.

However, by definition (S4), an integral beam headlamp (including

those with HID light sources) is one with an ``integral and indivisible

optical assembly'', and a headlamp that is ``not a replaceable bulb

headlamp * * *.'' In the event of damage to one component, such as the

lens, the entire unit, ballast and all, must be replaced. The cost to

replace an integral beam HID headlamp is substantially higher than the

cost of replacing a more conventional headlamp. The initial HID

headlamp permitted (as a result of NHTSA-initiated amendments to

Standard No. 108 to facilitate their introduction) was an integral-type

design. At the time, it was unknown how to define HID sources as

replaceable bulb light sources. The agency is now furthering HID

headlamp technology by defining HID's as ``replaceable light sources'',

so that headlamp components may be individually replaced. This

amendment to Standard No. 108 means that a vehicle manufacturer wishing

to offer HID headlamps now has a choice between two types, integral and

replaceable light source.

Comments in support of the NPRM were received from the American

Automobile Manufacturers Association (AAMA), Ford Motor Co., Hella,

Inc., Koito Manufacturing Co. Ltd., OSRAM Sylvania, Inc. (OSI), and

Stanley Electronic Co., Inc. Comments opposing the proposal were

received from the Insurance Institute for Highway Safety (IIHS) and

Advocates for Highway and Auto Safety (Advocates).

Proposed Amendments to Standard No. 108

S4 Definitions. NHTSA proposed to add a definition of ``filament''

to read:

Filament means that part of the light source or light emitting

element(s), such as a resistive element, the excited portion of a

specific mixture of gases under pressure, or any part of other

energy conversion sources, that generates radiant energy which can

be seen.

No comments were received on this issue and the proposed definition is

adopted.

Paragraph S7.7(i). The NPRM proposed amendments to paragraph

S7.7(i). Under the final rule published on November 28, 1995 (60 FR

58522), transferring HB type light sources to part 564, paragraph

S7.7(i) became paragraph S7.7(b). Under the final rule published today,

paragraph S7.7(b) becomes S7.7(d). The following summary of the

proposal adopts the nomenclature of the final rule, which does not

significantly differ from the proposal.

Paragraph S7.7(d) discusses the procedures for measuring maximum

power and luminous flux. This is followed by two new subparagraphs, the

first of which, S7.7(d)(1), applies specifically to seasoning

requirements for light sources with resistive element type filaments

and luminous flux measurement requirements for HB Type bulbs. The

second, S7.7(d)(2), applies to seasoning requirements for light sources

using excited gas mixtures as filaments or discharge arcs and

associated luminous flux measurement. As for seasoning of light sources

using other energy conversion sources, NHTSA will address this issue

when industry has identified such sources.

OSI recommended that the seasoning for resistive and excited-gas

light sources (including ballasts) should be one percent of rated life,

as set forth in SAE Recommended Practice J2009 FEB93 Discharge Forward

Lighting Systems (hereafter ``SAE J2009''). Ford also recommended that

seasoning for excited gas light sources (including ballast) be in

accordance with SAE J2009. Additionally, Ford recommended that

seasoning for resistive element type filaments be in accordance with

SAE J1383 APR85. NHTSA notes that its proposed amendments affecting

``seasoning'' are consistent with the OSI and Ford recommendations.

Ford found proposed paragraph S7.7(i) confusing and it suggested

changes which it felt would clarify NHTSA's intent. NHTSA concurs, and

has rewritten the provision as S7.7(b) (In addition to recommending

specific

[[Page 20498]]

requirements for the measurement of luminous flux for a light source

with a resistive element type filament, Ford did not object to the

NHTSA proposal to specifically cite seasoning requirements for light

sources using an excited gas mixture).

Regarding proposed paragraph S7.7(l)(7) which would require the

date of manufacture to be placed on the light source, Ford asked that

it not be adopted as it provides no safety benefit and because Standard

No. 108 does not require date of manufacture marking for any other

lamps or lighting equipment. NHTSA concurs, and the proposal is not

adopted.

Readers should note that proposed new paragraph S7.7(l) is adopted

as paragraph S7.7(e). New section S7.7(f) is added to state that, for

light sources that use light generated by gaseous discharge lighting

sources, seasoning shall be in accordance with section 4.0, and the

``rated laboratory life'' shall be determined in accordance with

sections 4.3 and 4.9 of SAE J2009.

S8 Tests and Procedures for Integral Beam and Replaceable Bulb

Headlighting Systems. In the NPRM, NHTSA proposed adding ``specific gas

mixture'' type light sources in the tests specified in S8 to replace

``non-filament type.'' There was no objection and S8 is amended as

proposed.

Other Issues Associated with Short Arc Discharge Lighting Systems.

The only regulatory requirement that NHTSA proposed that addressed the

issue of electrical shock was the marking of the ballast with an

appropriate warning. Stanley recommended the adoption of a universally

agreed upon marking system such as specified by the International

Standards Organization (ISO). However, NHTSA wishes to allow

manufacturers wide latitude in choosing their warnings regarding

electrical shock and has not followed Stanley's suggestion in the final

rule.

Proposed Amendments to Part 564

General. Ford would replace all references to ``filament'' with

``filament or discharge arc.'' NHTSA agrees, and this has been done

when the text could specifically refer to either. Also as indicated

previously, the definition of ``filament'' that was proposed to be

added to Standard No. 108, and it applies to part 564 by virtue of

Section 564.4 which incorporates definitions used in other NHTSA

regulations.

Section 564.2 Purpose. Ford recommended that this section not be

revised because both Appendix A and Appendix B have a common purpose;

``they merely accomplish it by requiring varying degrees of information

detail dependent upon the rated laboratory life of the light source.''

NHTSA disagrees; the intended purposes of Appendix A and Appendix B are

different. One purpose of the former is to assure that replacement

light sources are available and interchangeable. This is not a purpose

of Appendix B because long-life light sources need not be manufactured

for interchangeability purposes by many different aftermarket

suppliers. Because light sources with specifications filed under

Appendix B are expected to last the life of the vehicle, component

replacement would be necessitated primarily by damage. Thus it is

unlikely that the low demand for replacement components would be met by

other than manufacturers of the original equipment devices. This

distinction from Appendix A requires two different statements of

regulatory purposes in section 564.2.

Finally, Appendix B allows manufacturers to retain ballast design

parameters that may include proprietary manufacturing specifications,

whereas Appendix A requires disclosure of such aspects as they relate

to interchangeability.

Paragraph 564.5(a). Under the proposal, relevant manufacturers must

``furnish the information specified in appendix A or appendix B.'' Ford

suggested that this implied that manufacturers could file under either

Appendix when filing under Appendix B is allowable only for long-life

light sources. NHTSA has made an editorial change to clarify that

Appendix B is available only for long-life light sources, while both

Appendices are available for long- life light source information.

Appendix B. Commenters concurred with NHTSA's proposed benchmark

that not less than 2,000 hours of rated laboratory life is a suitable

designation of a long-life light source. In accordance with the

proposal, in the final rule the manufacturer of such a light source may

provide the lesser amount of information that will be required by

Appendix B, but, at its option, can make its submission under Appendix

A. In either event, a replaceable light source which is the subject of

information submitted to Docket No. 93-11 is required to comply with

Standard No. 108.

Stanley commented that a clear definition of ``life'' was not

provided in the NPRM, and recommended that ``life'' of a light source

be defined in terms of luminous flux maintenance. NHTSA concurs that an

explanation is desirable, since Standard No. 108 and Part 564 both

indicate that manufacturers may optionally furnish the information

specified in Appendix B, if the ``rated average laboratory life'' is

not less than 2,000 hours. The SAE has addressed this issue in sections

4.3 and 4.9 of SAE J2009. These sections specify procedures and tests

to determine life of the total HID system measured in both hours and

starting cycles. NHTSA is adopting the term used there, ``rated

laboratory life.'' In so doing, it also examined the definition of

``rated average laboratory life'' which appears in SAE Standard J1383

JUN90. It found that SAE J1383 JUN90 was suitable for incandescent

light sources where lumen drop off occurs at a relatively steady rate

over life, but that HID system lumens drop rapidly during the initial

burning hours and then, later, tend toward a more level rate of drop.

In Koito's view, Appendix B is not necessary. It believes that all

light source submittals to part 564, including HIDs, and regardless of

the rated laboratory life, should contain the information required in

Appendix A. It indicated that the life in hours of an HID light source

will vary with the ballasts combined with it. Therefore, life in hours

for an HID light source is essentially meaningless if the original

ballast is changed to another type of ballast. NHTSA understands this.

It is for this reason that NHTSA is adopting the language proposed in

the NPRM that Item III of Appendix B specifies the rated laboratory

life of the light source/ballast combination instead of that of the

light source alone. Item IV of Appendix B of this final rule reflects

this requirement. Appendix B was specifically intended to accommodate

all ballasts that are functionally interchangeable with a light source

but different in design. New paragraph S7.7(e)(4) of Standard No. 108,

adopted in this final rule, requires that each ballast filed with a

light source bear permanent markings that indicate the rated laboratory

life of the combination. Any part 564 submittal for a light source

requiring ballasts for operation must include information that

specifically identifies all ballasts that will be used with the light

source. Substitution of a ballast other than that identified with the

light source in part 564 is not permitted.

It is important that ballast information be submitted. NHTSA

considers the electronic ballast along with the transparent envelope

containing a specific mixture of gases under pressure (the discharge

bulb) to be an integral part of the light source system, although the

bulb and ballast may be separate components. Furthermore, in

determining compliance with Standard No. 108, testing of the light

source

[[Page 20499]]

without a designated ballast would be difficult if not impossible.

NHTSA has decided not to act upon Koito's recommendation that all

light source submittals (including HID) be required to fulfill all

informational requirements of Appendix A. The intent of Appendix A is

to ensure that sufficient technical information is available to

replacement light source manufacturers so that they may manufacture

identical replacement light sources. NHTSA has decided that requiring

the Appendix B submitter to provide all the information required in

Appendix A is unnecessary if the manufacturer provides rated laboratory

life data supporting a light source and ballast life of 2,000 hours or

more.

Ford recommended that Section I of Appendix A be added to Appendix

B (``Filament Position Dimensions and Tolerances Using Either Direct

Filament Dimensions or the Three Dimensional Filament Tolerance Box'').

Ford also recommended that Appendix B require specification of the

electrode position dimensions and tolerances for light sources using

excited gas mixtures as filaments. Ford stated that the mid-point of

the electrode separation distance would provide a comparable dimension

``A'' of Figure 8 to be utilized in Standard No. 108's section S9

Deflection test for replaceable light sources. NHTSA concurs with this

recommendation since, as Ford stated, the mid-point of the electrode

separation distance would provide a comparable dimension ``A'' which is

required to support the bulb deflection test for replaceable light

sources (S9). NHTSA has accordingly amended Section I of Appendix B as

adopted.

Finally, the reader should note that the conforming amendments to

paragraphs 564.5(a) and (c) reflect the agency's recent amendment of

paragraph S7.7 of Standard No. 108 and 564.5(a) and (c) to transfer HB

type replaceable light sources to Docket No. 93-11 (November 28, 1995;

60 FR 58522).

Comments in Opposition

IIHS opposed the rulemaking action because HID light sources are

more expensive to replace than other light sources and recommended that

the agency not permit the use of increasingly expensive lighting

systems on motor vehicles without conducting a parallel rulemaking to

reinstate a no- damage 5 mph bumper standard. Advocates, too, believed

that the replacement cost for HID headlamp systems ought to be a

central consideration of this rulemaking. NHTSA notes that HID light

sources are permitted in integral beam lighting systems, and will

continue to be so used even if they are not permitted in replaceable

bulb systems. However, the proposal to allow them in such systems is

being adopted because there are no safety disbenefits in allowing them.

The use of replaceable light source HID lighting systems as an

alternative to non-replaceable ones or to resistive element type

filament lighting systems is an issue of the marketplace, not of

safety.

Advocates disagreed with NHTSA that this rulemaking would reduce

costs both to manufacturers and consumers. In its view, NHTSA's

rationale for cost reduction is based upon the fact that HID headlamps

might not have to be replaced for the life of the vehicle and

consequently is not an adequate evaluation of the costs and benefits

accruing to consumers from the institution of HID headlamp systems.

NHTSA's rationale for cost reduction is intended in the context of

HID headlamp systems. In an integral beam system using HIDs, all

headlamp parts must be replaced when a component fails or is damaged,

even for something as simple as a cracked lens. Allowing HID's to be

used in replaceable bulb headlamp systems would permit separability and

the replacement of individual components at significant cost savings to

the consumer. Repair costs for damaged HID headlamps ought to be

significantly reduced if lamp bodies, discharge bulbs and ballasts can

be individually serviced, instead of being replaced as part of a

headlamp assembly. In addition, it is probable that minor damage would

be repaired (such as a cracked lens) that could degrade headlamp

performance if there is an economic incentive not to defer correction

until required to do so, either by failing performance or state motor

vehicle inspection.

Advocates also argued that the rulemaking was mischaracterized as

``non-significant.'' The rulemaking is properly characterized under DOT

policies and procedures. The final rule prescribes an alternative,

optional, headlighting system, and results in no additional costs or

burdens upon any regulated person or upon the public.

Finally, Advocates disagreed with the agency's decision not to

regulate ultraviolet radiation (UV) and electric shock, and recommended

that a supplementary NPRM be issued addressing the possible threat to

human health and safety through UV emissions and high voltages.

There appears to be no current need to do so, other than requiring

a warning marking on the ballast. NHTSA addressed these concerns in the

preamble to the proposal (see 60 FR at 31942). In that discussion,

NHTSA noted that SAE J2009 recognizes UV radiation and electric shock

as potential safety hazards. To address the hazard of UV radiation, the

lighting community has developed HID bulbs that include an additional

transparent envelope which is a UV filter. Other innovative design

solutions are being considered to prevent UV emissions. The need for

high voltage shock safety is also recognized by the SAE document. These

are design and testing issues for the manufacturer. NHTSA will monitor

them and propose rulemaking if it appears to be required for health and

safety.

Effective Date

Since the final rule does not impose any additional burden and is

intended to afford an alternative to existing requirements, it is

hereby found that an effective date earlier than 180 days after

issuance of the final rule is in the public interest. The final rule

(i.e., the amendments to the Code of Federal Regulations and the

requirements specified therein) is effective 30 days after its

publication in the Federal Register.

Rulemaking Analyses

Executive Order 12866 and DOT Regulatory Policies and Procedures

This rulemaking action has not been reviewed under Executive Order

12866. It has been determined that the rulemaking action is not

significant under Department of Transportation regulatory policies and

procedures. The effect of the rulemaking action is to allow an

alternative headlighting system. It will not impose any additional

burden upon any person. The final rule will reduce costs both to

manufacturers and consumers. Because ballasts will no longer have to be

integral with the light source, manufacturers may use a simpler, less

expensive connector. Consumers may replace separate elements of an HID-

replaceable light source headlamp system as compared with the present

regulation which requires replacement of the whole unit. Impacts of the

rule are, therefore, so minimal as not to warrant preparation of a full

regulatory evaluation.

Regulatory Flexibility Act

The agency has also considered the effects of this rulemaking

action in relation to the Regulatory Flexibility Act. I certify that

this rulemaking action would not have a significant economic

[[Page 20500]]

effect upon a substantial number of small entities. Motor vehicle and

lighting equipment manufacturers are generally not small businesses

within the meaning of the Regulatory Flexibility Act. Further, small

organizations and governmental jurisdictions will not be significantly

affected as the price of new motor vehicles will not be impacted.

Accordingly, no Regulatory Flexibility Analysis has been prepared.

Executive Order 12612 (Federalism)

This action has been analyzed in accordance with the principles and

criteria contained in Executive Order 12612 on ``Federalism.'' It has

been determined that the rulemaking action does not have sufficient

federalism implications to warrant the preparation of a Federalism

Assessment.

National Environmental Policy Act

NHTSA has analyzed this rulemaking action for purposes of the

National Environmental Policy Act. The rulemaking action will not have

a significant effect upon the environment as it does not affect the

present method of manufacturing motor vehicle lighting equipment.

Civil Justice Reform

This rulemaking action will not have any retroactive effect. Under

49 U.S.C. 30103, whenever a Federal motor vehicle safety standard is in

effect, a state may not adopt or maintain a safety standard applicable

to the same aspect of performance which is not identical to the Federal

standard. Under 49 U.S.C. 30163, a procedure is set forth for judicial

review of final rules establishing, amending, or revoking Federal motor

vehicle safety standards. That section does not require submission of a

petition for reconsideration or other administrative proceedings before

parties may file suit in court.

Paperwork Reduction Act

The reporting and record keeping requirement associated with part

564 have been approved by the Office and Management and Budget in

accordance with 44 U.S.C. chapter 35. The OMB control number is 2127-

0563.

(a) If other than an HB Type, the light source shall be marked with

the bulb marking designation specified for it in compliance with

Appendix A or Appendix B of part 564 of this chapter. The base of each

HB Type shall be marked with its HB Type designation. Each replaceable

light source shall also be marked with the symbol DOT and with a name

or trademark in accordance with paragraph S7.2.

(b) The measurement of maximum power and luminous flux that is

submitted in compliance with Appendix A or Appendix B of part 564 of

this chapter shall be made in accordance with this paragraph. The

filament or discharge arc shall be seasoned before measurement of

either. Measurement shall be made with the direct current test voltage

regulated within one quarter of one percent. The test voltage shall be

12.8v. The measurement of luminous flux shall be in accordance with the

Illuminating Engineering Society of North America, LM-45, IES Approved

Method for Electrical and Photometric Measurements of General Service

Incandescent Filament Lamps (April 1980); shall be made with the black

cap installed on Type HB1, Type HB2, Type HB4, and Type HB5, and on any

other replaceable light source so designed; and shall be made with the

electrical conductor and light source base shrouded with an opaque

white cover, except for the portion normally located within the

interior of the lamp housing. The measurement of luminous flux for the

Types HB3 and HB4 shall be made with the base covered with a white

cover as shown in the drawings for Types HB3 and HB4 filed in Docket

No. 93-11. (The white cover is used to eliminate the likelihood of

incorrect lumen measurement that will occur should the reflectance of

the light source base and electrical connector be low).

(c) The capsule, lead wires and/or terminals, and seal on each Type

HB1, Type HB3, Type HB4, and Type HB5 light source, and on any other

replaceable light source which uses a seal, shall be installed in a

pressure chamber as shown in Figure 25 so as to provide an airtight

seal. The diameter of the aperture in Figure 25 on a replaceable light

source (other than an HB Type) shall be that dimension furnished for

such light source in compliance with Appendix A or Appendix B of part

564 of this chapter. An airtight seal exists when no air bubbles appear

on the low pressure (connector) side after the light source has been

immersed in water for one minute while inserted in a cylindrical

aperture specified for the light source, and subjected to an air

pressure of 70kPa (10 P.S.I.G.) on the glass capsule side.

(d) The measurement of maximum power and luminous flux that is

submitted in compliance with section VII of Appendix A of part 564 of

this chapter, or section IV of Appendix B of part 564 of this chapter,

shall be made with the direct current test voltage regulated within one

quarter of one percent. The test voltage shall be 12.8v. The

measurement of luminous flux shall be in accordance with the

Illuminating Engineering Society of North America, LM 45; IES Approved

Method for Electrical and Photometric Measurements of General Service

Incandescent Filament Lamps (April 1980). The filament of a replaceable

light source shall be seasoned before such measurement. The white

covers are used to eliminate the likelihood of incorrect lumens

measurement that will occur should the reflectance of the light source

base and electrical connector be low.

(1) For a light source with a resistive element type filament,

seasoning of the light source shall be made in accordance with section

2.9 of SAE Standard J1383 APR85 Performance Requirements for Motor

Vehicle Headlamps. The measurement of luminous flux shall be made with

the black cap installed on Type HB1, Type HB2, Type HB4, and Type HB5

light sources, and on any other replaceable light source so designed,

and shall be made with the electrical conductor and light source base

shrouded with an opaque white colored cover, except for the portion

normally located within the interior of the lamp housing. The

measurement of luminous flux for Type HB3 and Type HB4 shall be made

with the base covered with the white cover shown in the drawings for

Types HB3 and HB4 filed in Docket No. 93-11.

(2) For a light source using excited gas mixtures as a filament or

discharge arc, seasoning of the light source system, including any

ballast required for its operation, shall be made in accordance with

section 4.0 of SAE Recommended Practice J2009 FEB93 Discharge Forward

Lighting Systems. With the test voltage applied to the ballast input

terminals, the measurement of luminous flux shall be made with the

black cap installed, if so designed, and shall be made with an opaque

white colored cover, except for the portion normally located within the

interior of the lamp housing.

(e) If a ballast is required for operation, each ballast shall bear

the following permanent markings:

(1) Name or logo of ballast manufacturer;

(2) Ballast part number or unique identification;

(3) Part number or other unique identification of the light source

for which the ballast is designed;

(4) Rated laboratory life of the light source/ballast combination,

if the information for the light source has been filed in Appendix B of

part 564 of this chapter;

(5) A warning that ballast output voltage presents the potential

for severe electrical shock that could lead to permanent injury or

death;

(6) Ballast output power in watts and output voltage in rms volts

AC or DC; and

(7) The symbol `DOT'.''

(f) For light sources that use excited gas mixtures as a filament

or discharge arc, the ``rated laboratory life'' shall be determined in

accordance with sections 4.3 and 4.9 of SAE Recommended Practice J2009

FEB93 Forward Discharge Lighting Systems.

(g) After the force deflection test conducted in accordance with

S9, the permanent deflection of the glass envelope shall not exceed

0.13 mm in the direction of the applied force.
