TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letters of March 7 and May 15, 1968, to Mr. George C. Nield, concerning the requirements for motorcycle headlamps as specified in Motor Vehicle Safety Standard No. 108.

On motorcycles, Standard No. 108 permits the use of unscaled headlamps conforming to SAE Standard J584. You will note that this SAE standard does not reference bulb sockets conforming to SAE Standard J567, which is intended to insure functional compatibility between bulb sockets and the bulbs listed in SAE Standard J573. Therefore, the bulbs used in motorcycle headlamps conforming to SAE Standard J584 need not conform to SAE Standard J573.

Thank you for writing.
