Dear Mr. Scully: This is in reply to your letter of September 25 to Mr. Lewis C. Owen o this Office concerning the mounting of front clearance lamps on trucks and buses over 80 inches in width.; You are correct in your interpretation that these lamps must be mounte to indicate the overall width of the vehicle and as near the top as practicable. The width and height of the body in relation to that of the cab on a van type truck governs the proper location, therefore, each application must be judged individually. However, you are correct that the proper location should be the top front corners of the body when the height of the body is significantly higher than the cab.; Since this same question has been directed to us repeatedly and som manufacturers are installing cab mounted lights and others body mounted lights on quite similar vehicles, we anticipate that this aspect will be addressed in future rulemaking actions.; Sincerely, E. T. Driver, Director, Office of Operating Systems, Moto Vehicle Programs;
