Dear Mr. Scully: This is in reply to your letter of October 25, 1983, to Mr. Cavey o this agency asking for a copy 'of an NHTSA ruling issued sometime ago which supposedly permits the triple identification lights normally mounted on the top rear center line of semi-trailers to be mounted at the lower sill location.'; I enclose a copy of an interpretation furnished the State of Wisconsi on June 18, 1981, concerning this practice by Fruehauf Corporation. In summary, Fruehauf demonstrated to us the impracticability of mounting the lights at the top of a body with high-opening doors and a narrow header (chiefly because of vulnerability of the wiring).; The agency's interpretation was limited to vehicles of that specifi configuration, and was not intended to apply to semi-trailers in general.; If you have any further questions, we shall be glad to answer them. Sincerely, Frank Berndt, Chief Counsel
