ABSTRACT:
A windshield wiper-headlight control circuit which actuates the headlights of an automobile in response to an automobile driver turning on the windshield wipers. The control circuit then maintains the headlights in an actuated state, independent of the positioning of the windshield wipers, and automatically turns-off the headlights when the automobile ignition is turned-off. The control circuit includes an ignition branch, a windshield wiper branch, and at least one headlights branch. A relay coil is located in the ignition branch and controls relay switches in the ignition branch and headlight branches. A diode controls current flow from the windshield wiper branch to the relay coil.
