Abstract: A transistorized flasher circuit having a set of normally closed relay contacts in series with a lamp load across a voltage source. The relay contacts are periodically opened and closed to flash the load by an oscillator which includes a relay coil which controls the relay contacts and includes the emitter and collector electrodes of a transistor connected in series. The base electrode of the transistor is connected between a capacitor and a resistor which are in series across the source. A discharge path is provided for the capacitor when the relay coil is energized. The transistor is turned on to energize the coil when the capacitor is charged and is turned off to deenergize the coil when the capacitor is discharged, whereby the source is periodically connected directly to the lamp load for flashing the lamps as the capacitor is periodically charged and discharged.
