Abstract

A control system for automatically turning on the headlights (and parking lights) of a vehicle has an input section that includes the ignition switch, the manually operated windshield wiper switch, and condition responsive light sensor and moisture sensor switches. These switches operate through a logic circuitry through an output section to turn on and to keep turned on the lights when any of certain switch combinations are turned on: a) ignition, windshield wiper, light sensor and moisture sensor; b) ignition, windshield wiper and light sensor; c) ignition, windshield wiper and moisture sensor; d) ignition and windshield wiper; e) ignition, light sensor and moisture sensor; f) ignition and light sensor; or g) ignition and moisture sensor. In the event that the windshield wiper is turned off the light level sensor causes the lights to be turned off. The windshield wipers are turned on with the following switch combinations even though the manual windshield wiper switch is turned off: a) ignition, light sensor and moisture sensor; or b) ignition and moisture sensor.
