Dear Mr. Abbott:

This is in response to your letter dated June 27, 1978, asking whether fog lamps mounted to the surface of a vehicle bumper are removed prior to testing for compliance with Part 581, Bumper Standard.

Vehicles subject to the requirements of Part 581 must comply with the protective criteria of section 581.5(c) (49 CFR 581.5(c)) when tested under the conditions stated in section 581.6 (49 CFR 581.6). The test conditions make no provision for removal of fog lamps prior to testing. As was the case under Federal Motor Vehicle Safety Standard 215, Exterior Protection, the Part 581 test procedures provide for removal only of trailer hitches before testing. With the added exception of license plate brackets, excluded from the requirements of Part 581 by interpretation (42 FR 24056; May 12, 1977), other equipment (including fog lamps) attached to the bumper system prior to sale of the vehicle to its first purchaser must meet the damage limitations of the standard.

Sincerely,

Joseph J. Levin, Jr. Chief Counsel

Dear Mr. Levin:

Cars & Concepts, Inc. is preparing a prototype Dodge Omni "Rally" for a 1980 model year production program. It is proposed that Chrysler Corporation ship completed vehicles to one of our facilities where we would attach certain pieces of equipment comprising the "Rally" package. The vehicles would then be shipped back to Chrysler for distribution through their normal channels. Included in the "Rally" package is a pair of Cibie C-95 white fog lamps. These would be made inoperable for highway use by means of an easily removable fuse mounted to the instrument panel. The lamps would be mounted to the top surface of the bumper (to comply with certain state regulations) and closely enough to the vehicle centerline to avoid the normal beam path of the headlights. To avoid contact with the grille when the bumper is fully compressed, it will be necessary to mount the lamps close to the bumper face placing them in potential danger of being damaged in a 5 mph pendulum test. It is our understanding that under the provisions of FMVSS #215 such items were routinely removed before testing. We are concerned that the status of accessory lighting would change under FMVSS part 581 and would like a clarification of this.

Thank you for your assistance in this matter.

Sincerely,

Glenn Abbott Design
