Interpretation ID: nht91-1.36

DATE: February 8, 1991

FROM: J.C. Brown -- President, MidAmerica Design Service

TO: Taylor Vinson -- Chief Counsel, NHTSA

TITLE: None

ATTACHMT: Attached to letter dated 3-7-91 from Paul Jackson Rice to J.C. Brown (A37; Std. 108)

TEXT:

MidAmerica Design Service is being asked to develop a high mounted stop light and turn signal to be installed into the door of over the road trailers.

This light will be wired to the existing system as an "add on".

After reviewing FMV-108, I can find no reference to any high mounted stop light for trailers in any form. Therefore, it appears, that as long as I add to the existing system and not eliminate any standard lighting, we will be in compliance with the standards.

Please forward to me your opinion and any other steps I must take to ensure compliance.
