TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of September 26, 1968, to Mr. Robert M. O'Mahoney, Assistant Chief Counsel, concerning clearance lamp mounting on bodies installed on chassis-cabs.

It is required by Federal Motor Vehicle Safety Standard No. 108 that clearance lamps be mounted as near as practicable to the upper left and right extreme edges of the vehicle. The cab mounted clearance lamps shown on your drawing CA1030-40, dated September 24, 1968, being mounted approximately 16 inches inboard of the extreme body width, do not appear to be as near as practicable to the extreme edges of the vehicle. Lamps mounted at the right and left extreme edges of the widest part of the body panel would meet the requirements. The mounting height of these lamps should be as high as practicable without causing objectionable glare in the rear view mirror. Retention of cab mounted clearance lamps is optional.

With respect to the requirements of Standard No. 108, I must point out that this Bureau does not issue approval on items of lighting equipment or on vehicle designs incorporating this equipment. Therefore, comments of this Bureau are for information purposes only and in no way relieve any vehicle manufacturer from his responsibility for certifying that the assembled vehicle meets the requirements of Standard No. 108.
