ABSTRACT:
A vehicular light control system for controlling the illumination of a vehicle's external directional/turn signaling and/or hazard warning lights, by controlling continuous illumination of pairs of the brightest signal filaments of either dual or single filament bulb designed vehicles, where such bulbs were previously flash only and underutilized. The system operates to control the brightest filaments when the operator wishes to draw attention to the vehicle for safety, or for visibility and utility purposes, without the same system negatively affecting normal operation of existing turn signal/hazard warning systems. The system automatically and manually controls the light output as desired by the vehicle operator, incorporates the vehicle's internal turn signal bulb-out indication subsystem to continuously monitor the target bulbs for an open circuit/burn out event, and employs an automatic safety reconnect feature, a failsafe which reconnects all factory wiring with factory bulbs instantaneously with any accidental or intentional system power loss.
