Incandescent Lamp Flasher using IRF510 HexFET

The circuit Incandescent Lamp Flasher in Figure is built around two power FETs, which are configured as a simple astable multivibrator to alternately switch the two lamps on and off. The R&C values given in the Parts List sets the flash rate to about 1⁄3 Hz. By varying either the resistor or capacitor values almost any flash rate can be achieved.
