TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of September 5, 1973, to Mr. Schneider asking whether you may furnish side turn signal lamp for inter-city buses at the rear wheels, and if so, the required color.

It is correct that there are no Federal safety requirements for side turn signal lamps. Therefore, there is no Federal prohibition against your providing such a lamp, and such restrictions as may exist would be those imposed by the States.

Rear mounted turn signal lamps under Federal Standard No. 108 may be either red or amber.
