TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of October 14, 1970, to Mr. Douglas W. Toms, Director, National Highway Safety Bureau requesting an interpretation on the "marker blink switch" relative to Federal Motor Vehicle Safety Standard No. 108.

The use of this switch does not violate the requirements of paragraph S3.5 of Standard No. 108, and is permitted by paragraph S3.1.2.

Flashing lights for signaling purposes in a highly controversial subject with many proponents for, and many against, their use. This aspect is being clarified in a soon-to-be-published amendment to Standard No. 108, and will be addressed further in a forthcoming notice of proposed rule making on the same standard.
