CERTAIN TRANSIT BUSES WITH AN OPTION FOR DECELERATION LIGHTS DO NOT MEET ALL THE REQUIREMENTS OF FMVSS NO. 108, “LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT.” THE DECELERATION LIGHTS ARE LOCATED ON THE REAR CENTER OF THE BUS, ABOVE THE REAR ENGINE DOOR. THEY ARE PROVIDED AS A MEANS OF ALERTING VEHICLES TRAVELING BEHIND THE BUS THAT IT IS SLOWING DOWN AND MAY BE PREPARING TO STOP. ALSO, THE DRIVER ACTIVATED, FLASHING HOODLUM LIGHTS, IS TO ALERT THE PUBLIC/POLICE TO A DANGEROUS SITUATION OCCURRING IN THE BUS FOR WHICH THE DRIVER REQUIRES ASSISTANCE. TWO OF THESE LIGHTS ARE LOCATED ON THE FRONT OF THE BUS AT EACH END OF THE DESTINATION SIGN AND TWO AT THE REAR OF THE BUS BELOW THE LEVEL OF THE ROOF MARKER LIGHTS. THEY FLASH IN AN ALTERNATING PATTERN FROM SIDE TO SIDE. THE STANDARD REQUIRES THAT THESE LAMPS SHALL BE WIRED TO BE STEADY BURNING.
