Dear Mr. Borovik: This is in reply to your letter of August 7, 1979, asking whethe 'trailer warning lamps [should] flash or be steady-burning' when the towing vehicle's hazard warning system is actuated and the service brakes are applied.; Federal Motor Vehicle Safety Standard No. 108 does not require trailer to be equipped with hazard warning signal lamps, and you may design your trailer tow electrical package without reference to it. Lack of Federal regulation in this area, however, means that each State may set its own requirements, and you should ascertain whether such exist before finalizing your design.; Sincerely, Frank Berndt, Chief Counsel
