Dear Mr. Wagar:

This is in reply to your letter of July 20, 1999, to Taylor Vinson of this Office asking two questions on motor vehicle lighting, as clarified by your conversation with him on October 13, 1999.

Comments on Draft of Regulations to Implement Bill S00577

New York has enacted Bill S00577 on July 29, 1998, effective June 1, 1999, which provides for a reduction in insurance premiums for "motor vehicles weighing in excess of ten thousand pounds" if the vehicles are "equipped with factory installed auxiliary running lamps." The purpose of the legislation is "to reduce accidents by increasing vehicle visibility during the day and night." You have submitted for our review and comment the draft by the New York State Insurance Department of an implementing regulation, and a copy of your memorandum of July 1 to Neal Schoen "of our Legal Bureau" with your own opinions and comments.

We greatly appreciate your seeking our advice before the State adopts a regulation that might conflict with preemptive Federal requirements. Under 49 U.S.C. 30103(b)(1), a state may prescribe a standard applicable to the same aspect of performance of a motor vehicle only if the standard is identical to the Federal standard. The applicable Federal requirements are those of 49 CFR 571.108, Standard No. 108, Lamps, Reflective Devices and Associated Equipment. Although the aspect of performance involved is the conspicuity of large vehicles, which the agency has addressed through its requirements for conspicuity marking, New York has not adopted a "standard" that requires the installation of additional conspicuity equipment, but has simply authorized a reduction in insurance premiums for vehicles equipped with auxiliary running lamps. Generally, we do not view this sort of program as preempted by Standard No. 108. However, we are concerned about the specifics of the New York provision.

Specifically, Standard No. 108 seeks to enhance conspicuity of heavy trucks and buses by allowing their manufacturers to equip them with daytime running lamps (DRLs) meeting the requirements of S5.5.11, and by requiring them to be equipped with side marker lamps and reflectors (Tables I and II) and with conspicuity schemes (S5.7). New York offers an incentive to reduce insurance premiums if the visibility of a large vehicle is enhanced day and night with factory installed "auxiliary running lamps." Although New York is not preempted under Federal law from encouraging the installation of such lamps by mandating reduced insurance premiums, the lamps must not be inconsistent with the Federal requirements of Standard No. 108.

The Insurance Department would allow the system to be mounted along the sides and rear of the vehicle, or trailer, at intervals of not more than ten feet. The system would be automatically activated with the ignition of the vehicle's engine and remain so while the vehicle was in operation. The system would flash automatically when the turn/hazard warning system signals are activated, and increase intensity when the brakes are applied. Red lights used as part of the system would not be visible from the front of the vehicle.

This system would not be acceptable under Standard No. 108. Paragraph S5.5.10(d), in essence, requires auxiliary lamps of this nature to be steady burning (unless they supplement lamps that S5.5.10 requires or permits to flash), thus they could not flash with the hazard warning and turn signals. Further, an auxiliary lighting device or system must not impair the effectiveness of lighting equipment required by the standard (S5.1.3).

Your memorandum would modify the Insurance Department's proposed operating scheme by specifying that the lamps be no closer than four feet apart on center, consistent with the height required for side marker lamps. The auxiliary running lamps would essentially be extra side marker lamps, and would be amber in color, and comply with side marker lamp performance. The lamps would automatically illuminate when the head lamps or required side marker lamps are illuminated and would not flash. Finally, the added lamps would not be visible from directly in front or to the rear of the vehicle.

Your suggested modifications largely address the compliance problems inherent in the Insurance Department proposal. We note, however, that S5.5.10(b) of Standard No. 108 permits side marker lamps to flash for signaling purposes. Thus, the lamps that New York is specifying as auxiliary side marker lamps may flash for signaling purposes. However, individual lamps to the rear of the trailer midpoint must be red, rather than amber, to avoid an impairing effect upon the vehicle's red rear side marker lamps. Your phrase "consistent with the height required for side marker lamps" covers a wide range of mounting heights. Standard No. 108 does not specify an upper mounting height limit for side marker devices on large trucks, though it does establish a limit of 60 inches above the road surface for the red side markers mounted at the rear of trailers. We also advise that the lamps should not be mounted directly on the conspicuity tape or reflectors with which these large vehicles are required to be equipped by S5.7 of Standard No. 108. Finally, we note that your modification would result in the auxiliary running lamps operating only when the headlamps are activated, rather than when the ignition is on. This appears contrary to the Legislature's intent to increase visibility by day, as well as by night.

Our Comments on the "Total Vehicle Safety Signalight System"

Your second question deals with the SAFE Foundation's lighting proposal, as shown on a tractor semi-trailer. Your concerns include flashing red and amber lights on the side, and additional amber lamps in a triangular formation on the rear of the vehicle.

As you know, under S5.1.3 of Standard No. 108, auxiliary lighting is prohibited if it impairs the effectiveness of lighting equipment required by Standard No. 108. With this in mind, we have reviewed SAFE Foundation's "Total Vehicle Safety Signalight System" ("the System")(an invention of Harold Caine as presented by his attorney, Samson Helfgott) as described in your letter, and our comments are given below. For purposes of this interpretation, we assume that none of the System's lamps are intended to serve as either the front or rear side marker lamp required by Standard No. 108. We also assume that the System is capable of being operated both during the day and night.

The System consists of:

1. Side mounted lamps:

Element A: at least four steady burning amber lamps on each side, facing to the side, spaced every 7 to 10 feet with three equal spaces between them: to illuminate whenever the vehicle is in operation, but extinguished when the service brakes are applied. In addition, when a turn signal is operating, the lamps on the turn-indicated side of the vehicle would flash also.

The System's amber side lamps are similar in color and function to front side marker lamps and reflectors that are required by Standard No. 108, and intermediate side marker lamps and reflectors that must be on vehicles whose overall length is 30 feet or more. Accordingly, we regard them as supplementary side marker lamps. On July 20, 1994, we advised Mr. Helfgott that supplemental lighting devices to the rear of the midpoint of a vehicle must be red. However, we understand that many supplemental marker systems that are in use and which consist of discrete lamps or reflectors are, in fact, amber. Accordingly, we do not object to the System's use of amber lamps or reflectors located to the rear of the midpoint, provided they are also located forward of the required red side marker lamps. Their steady burning use does not impair any other lamps. Standard No. 108 permits side marker lamps to flash with the turn signal lamps, and this feature would not cause an impairment of required lighting equipment, even if the required side marker lamps do not flash.

Element B: at least four steady burning red lamps on each side, facing to the side, spaced every 7 to 10 feet, located directly above the four amber lamps: to illuminate when the service brakes are applied.

The red side lamps are intended to indicate that the vehicle is braking. The lamps that Standard No. 108 requires to indicate braking are located on the rear. It is our opinion that a supplementary lighting scheme which indicates braking from three or four lamps spaced along the side of a large vehicle can detract from safety rather than add to it by confusing a driver with a novel and unfamiliar lighting scheme. This is of particular concern in situations where the lights will be visible to drivers approaching (rather than following)the vehicle on two-lane roads. When an array of lamps causes confusion, the effectiveness of all a vehicle's lighting system can be said to be impaired.

2. Rear mounted lamps:

Element A: three steady burning amber lamps in a triangular array on the rear, facing to the rear: to illuminate whenever the vehicle is in operation, but extinguished when the service brakes are applied.

Standard No. 108's lighting scheme establishes red and white as the color of steady burning lamps on a vehicle's rear, and amber and white for the front. The use of an amber array on the rear removes the certainty that red provides, and would impair the effectiveness of all red lamps on the rear.

Element B: three steady burning red lamps in a triangular array on the rear, facing to the rear: to illuminate when the service brakes are applied.

These lamps are activated simultaneously with the required stop lamps and supplement them. The triangular array will be similar to that perceived on vehicles equipped with center high mounted stop lamps. Thus, we do not believe that this will create an impairment.

We have previously provided SAFE Foundation's attorney, Samson Helfgott, with interpretations of Standard No. 108 on June 30, 1989, and September 17, 1990. To the extent that these may seem inconsistent with the interpretation we are providing you, each of the letters was based upon the facts as we understood them at the time. The interpretation we are providing you is controlling, under the facts and assumptions of this letter.

We note that 49 U.S.C. 30103(b)(1) does not prohibit New York from disallowing use on its roads, even if NHTSA concludes that it would not impair required lighting equipment. Although a State cannot disallow optional types of lighting equipment specifically covered by Standard No. 108, such as daytime running lamps and motorcycle modulating headlamps, it is not precluded from regulating non-covered and additional lighting equipment (such as fog lamps and a non-impairing version of the TVSSS), even if they would be acceptable under S5.1.3.

If you have further questions, you may call Taylor Vinson of this Office (202-366-5263).
