Dear Mr. Watson: This is in response to your letter of January 29, 1976, requesting a interpretation of the requirements of S.6 of Federal Motor Vehicle Safety Standard No. 111 , *Rearview Mirrors*, as they apply to the manufacture of mobile homes with a GVWR of greater than 10,000 pounds.; The standard requires that these vehicles be equipped with outsid mirrors of unit magnification, *each with not less than 50 square inches of reflective surface*, on both sides of the vehicle. While you are free to provide additional mirrors, the standard clearly requires two mirrors each of which has at least 50 square inches of reflective surface. Substitution of a number of small mirrors for one or both of the 50 square inch mirrors is impermissible, even if a total reflective area of 50 square inches is provided.; If you require any further assistance, do not hesitate to write. Sincerely, Richard B. Dyson, Assistant Chief Counsel
