An auxiliary pedestrian crossing warning signal system for use in automobiles equipped with a main signal system including front and rear, left and right amber turn indicator lamps incorporates an alternating flasher into the main signal system via a relay to provide communication between a driver and a pedestrian in order to reduce vehicle-pedestrian collisions. An automatic shut-off timer is connected to the relay circuit for controlling the duration of the auxiliary system operation after the brake pedal is released. The auxiliary system is operated by a momentary pressure on a pushbutton switch mounted in the dashboard and by the application of pressure to the vehicle brake pedal, so that the auxiliary system operates only when the pushbutton is energized and the vehicle is stopped. In addition to the in-dash indicator lights, a pair of indicator lights can be mounted beside the pushbutton switch as an additional indication that the auxiliary system is in operation.
