Abstract: A direction signal circuit including a pair of electronic timers comprising a plurality of silicon controlled rectifiers and unijunction transistor relaxation oscillators interconnected with a direction signal switch to sequentially energize a plurality of left or right signal lamps to indicate a change of direction. The timers further include a transistor responsive to concurrent actuation of the direction signal switch and a brake pedal switch for simultaneously energizing all lamps on the side of the vehicle opposite the intended turn to indicate an impending deceleration of the vehicle in contemplation of the turn. The timers are also interconnected with a hazard warning switch to simultaneously flash all of the vehicle signal lamps to indicate an emergency or hazardous condition of the vehicle.
