ABSTRACT:
An automotive vehicle electrical circuit that, when the hazard warning switch is in the on position, provides for the front lamps on both sides of the vehicle to continue to flash on and off when the stop lamp switch is actuated to continuously illuminate the rear lamps on both sides of the vehicle. The invention enables a pre-existing lamp control circuit to be cost-efficiently adapted to this form of control with only relatively minor modifications, namely the addition of two diodes and a minor change to the pre-existing turn signal switch. The invention may also be used to advantage in the production of new vehicles.
