ABSTRACT:
A control circuit automatically provides power to the headlights of a vehicle once the windshield wipers have been turned on if the ignition switch is also turned on. Should the headlights already be turned on once the windshield wipers are turned on, the control circuit of the present invention has no effect on the operation of the headlights. However, should the headlight switch remain on after the ignition switch is turned off, an audible alarm is produced to alert the user of the vehicle that the headlights are still on.
