A vehicular lighting control system for controlling the illumination of a vehicle's external directional/turn signaling and/or hazard lighting, by controlling continuous illumination of pairs of the brightest filaments of single or dual filament bulb designed vehicles. The system controls to operate the brightest filaments when the operator wishes to draw attention to the vehicle for safety, or for visibility 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-failure indication subsystem to continuously monitor the target bulbs for any failure event, and employs a dynamic safety reconnect feature, an attribute which reconnects factory wiring with factory bulbs instantaneously with any signaling or hazards activation. The device employs a zero-system current drain, actual dual bulb activation/current consumption notwithstanding, for minimum environmental impact/maximum fuel conservation.
