Dear Mr. Buske: Your letter of September 3, 1971, to the Bureau of Motor Carrier Safet concerning the mounting of lamps on a body backplate has been referred to this Office for consideration and reply.; Federal Motor Vehicle Safety Standard No. 108 requires that lamps mee the applicable SAE Standards (including the photometric specifications) when tested as mounted on the vehicle. (See SAE J575c, Paragraph J.) The maximum angle from a line perpendicular to the longitudinal centerline of the vehicle that a lamp can be mounted and meet the applicable requirements depends upon the design and configuration of the lamp. We therefore recommend that you contact the manufacturer of your lamps for this maximum angle information.; Sincerely, E. T. Driver, Office of Operating Systems, Motor Vehicl Programs;
