Abstract
Abstract A combination floodlight, spotlight and flasher circuit is disclosed herein. The circuit is provided with a manual switch means, which will turn a spotlight to on, off, and flash, and turn the floodlight on, off, and to a battery saver position. The floodlight is operated through a unique inverter circuit and flasher circuit combination. Multiple combinations of switching modes make it possible to selectively accomplish various combinations of lights simultaneously.
