ABSTRACT:
Apparatus for operating exterior lights on an automotive vehicle under inclement weather conditions that includes an electronic switch responsive to a vehicle operator for selectively activating the vehicle windshield wipers under inclement weather conditions, and electronic circuitry responsive to the windshield wiper switch for automatically applying electrical power to the vehicle exterior lights. The electronic circuitry preferably comprises a latch circuit that is set by operator activation of the vehicle windshield wipers for maintaining illumination of the vehicle exterior lights even if the windshield wipers are later deactivated by the operator. The latch circuit is reset by operation of the vehicle ignition switch to disenable ignition at the vehicle engine. Thus, the vehicle exterior lights are activated and remain activated under inclement weather conditions that require operation of the windshield wipers.
