Dear Mr. Gravengood:
This is in reply to your letter of April 3, l989, to this Office enclosing samples of plastic lenses. Your company manufactures "heated lights" which appear beneficial in melting snow that accumulates on them in the winter months. In your letter, you stated:
"All lights, lenses, and materials to assemble the heated safety lights have already been certified and passed the Motor Vehicle Safety Standard No. l08. We have been advised by the National Highway Traffic Safety Administration that there is no motor vehicle safety standard no. for heated lights. In order for us to do business at the O.E.M. level we require a letter of approval from you to us that we may pass on to our customers so they may start ordering and we may start producing."
We have no authority to "approve" or "disapprove" items of motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act, an equipment manufacturer "approves" each of its own products that are subject to a Federal motor vehicle safety standard by certifying that it meets all applicable Federal motor vehicle safety standards, or (if it is a vehicle manufacturer), that the vehicle on which the lamp is installed, complies with the standards. However, we can advise you of the relationship of your product to Standard No. l08. This should prove helpful in dealings at the O.E.M. level.
There are two types of O.E.M. lighting equipment: lamps that are required by Standard No. l08, and supplementary lamps that do not come under its coverage. Although your product literature indicates that the highmounted heated taillamp supplements the original equipment lamp, it is not clear whether the heated signal lamp serves as the required signal lamp or is a supplement to the original equipment. Accordingly, this letter discusses how Standard No. l08 treats both original required and original supplemental lighting equipment.
If you are the manufacturer of original lighting equipment required by Standard No. 108, but not the manufacturer of the vehicle on which it is installed, the vehicle manufacturer, and not you, has the legal responsibility under the Act and Standard No. l08 of ensuring that the equipment complies with the standard, and of certifying that the vehicle meets all applicable Federal motor vehicle safety standards. As a practical matter, however, vehicle manufacturers generally insist that equipment manufacturers provide assurance that their products meet Federal standards, but the "certification" they may insist upon is not required by the Act. You are correct that there is no standard that applies to heated lamps as such. The Federal standard that applies is the one imposed by Standard No. l08 for the particular equipment item (taillamps or signal lamps in this instance).
If you are manufacturing a lamp as an original equipment supplement to required original lighting equipment, the burden remains on the vehicle manufacturer who installs it. The only restriction on a supplementary lamp that Standard No. l08 imposes is that it not impair the effectiveness of the required lighting equipment (paragraph S4.1.3). Your lamps "splice into" the wiring for the taillamps and "marker lamps", according to your product literature. Therefore, it is incumbent upon the vehicle manufacturer to ensure that this installation does not negatively affect the performance of the required taillamps and signal lamps, or otherwise impair its effectiveness. If the vehicle manufacturer determines that no impairment exists, then it may certify that its vehicles comply with all applicable Federal motor vehicle safety standards.
Observing that the product literature depicts the heated taillamp installed in the upper corners of a school bus body, we must also call attention to an additional provision of Standard No. l08. The location depicted is one that is frequently used for the clearance lamps required by Standard No. l08. Paragraph S4.4 of Standard No. l08 forbids the optical combination of clearance lamps and taillamps. Thus, your lamp cannot optically combine these two functions if it is to be used as new vehicle equipment.
Other enclosures to your letter indicate that at present the heated lamp is being installed on buses in use, that is to say, as non-original equipment. The requirements imposed by Standard No. l08 and the Act for aftermarket manufacturers of lighting equipment differ from those for original equipment. If the lamp you produce is intended to replace an original equipment certified lamp, it is considered replacement equipment. As a manufacturer of a replacement taillamp or signal lamp, the legal obligation to produce a complying equipment item falls squarely upon you, as does the certification responsibility. If the lamp is intended only to replace a supplemental lamp, you are not required to certify. However, there may be instances in which your lamp is interchangeable with original certified equipment, and even though you may not intend it as replaceable lighting equipment, you may encounter questions from state and federal authorities if it is not manufactured and certified in accordance with Standard No. 108.
Finally, you should be aware of your responsibilities under the Act in the event that your products do not comply with Standard No. l08, or incorporate a safety related defect (an example would be the inability of the lens to withstand the heat produced during the lamp's operation without warping or cracking). If you or this agency determine that a noncompliance or safety related defect occurs in any item of replacement equipment that you manufacture, you have the obligation to notify purchasers, and to remedy the problem through repair, repurchase, or replacement of the item. With respect to original equipment, this obligation falls upon the manufacturer of the vehicle on which it is installed.
If you have any further questions we shall be happy to answer them. We are returning your samples.
Sincerely,
Stephen P. Wood Assistant Chief Counsel for Rulemaking
