Brooking Industries' new FL-4OFIF flasher interface is designed specifically for the Ford Interceptor sedan and utility models. The unit holds the headlight shutters open allowing the high beams to flash in one of four patterns or randomly through all four. Plug-and-play connectors allow for easy installation without cutting factory wires. It connects by wiring the unit to power and connecting to the existing factory headlight plug. A constant 12 VDC auxiliary output circuit allows any other lighting to be run through the interface.
