Abstract
A flasher controller comprised of two integrating circuits, one functioning as a pulse width modulator and the other as a free running 50% duty cycle oscillator which in combination drive on a selective basis the base of one of two transistors in accordance with a pulsed voltage of predetermined frequency: the emitter of one transistor and the collector of the other are each connected to energize the solenoid of the power relay connected in series in a pre-existing automotive lamp circuit and thereby alternately open and close that circuit in accordance with the said pulsed voltage.
