Abstract
A control circuit is provided for controlling the warning lights on a vehicle having first and second composite brake/turn lights. The control circuit receives two composite input signals from the vehicle generated by operation of the vehicle's brake and turn signal controls. The control circuit jointly processes the composite input signals to separate the brake and turn indications in order to determine the operational state of the vehicle and generates composite output signals to control the composite brake/turn signals. In one embodiment, a braking pattern is applied to both composite brake/turn signals when the vehicle is braking only. When the vehicle is braking and turning simultaneously, a turn signal pattern is applied to one of the composite brake/turn lights and the other composite brake/turn light is turned on without modulation.
