Dear Mr. Miyazawa: This is in reply to your letter of April 28, 1979, asking two question with respect to certification of lighting equipment by use of the DOT symbol, as permitted by S4.7.2 of Federal Motor Vehicle Safety Standard No. 108.; Your first question is whether disassembled parts such as lenses screws, or bulbs must also be certified as conforming to all applicable Federal motor vehicle safety standards. The answer is no, only the completed lamp assembly must be so certified.; You have also asked 'in the case of lamp lens incorporated with refle reflector do we have to label the DOT label on this reflex reflector certifying it meets FMVSS?' The answer is yes. Although the lamp lens is not a required equipment item and not certified since it is only part of a lamp, the reflex reflector incorporated in it must be certified since the reflector is an item required by Standard No. 108.; I hope this answers your questions. Sincerely, Frank Berndt, Acting Chief Counsel
