Headlights "ON" control for motor vehicles
First Claim
1. A control apparatus for a vehicle having a windshield wiper means to clear the windshield operable to connect an electric power source to the vehicle headlights, taillights and electric powered means to operate the windshield wiper means of the vehicle only when the headlights are ON comprising:
- an ignition switch having START, RUN and OFF positions connected to the electric power source, first relay means having a solenoid electrically connected to said ignition switch to energize the solenoid when the ignition switch is in the RUN position, said first relay means having normally open switch means connected to the electric power source, headlights and taillights so that when the solenoid is energized, the switch means closes, thereby turning the headlights and taillights ON, windshield wiper switch means connected to said ignition switch operable in response to at least ON and OFF conditions to control operation of said electric powered means to operate the windshield wiper means, said windshield wiper means having a wiper actuator movable to ON and OFF positions, headlight switch means operable to selectively turn the headlights and taillights ON and OFF, said headlight switch means having a headlight actuator selectively movable to ON and OFF positions, second relay means connected to the electric power source and headlights and taillights, said second relay means having a solenoid connected to said windshield wiper switch means, said second relay means being actuated in response to operation of said wiper actuator in the ON position to complete an electrical circuit to the headlights and taillights and light responsive switch means connected to the ignition switch and said solenoid of said second relay means, said light responsive switch means operably turns the headlights ON when the light intensity surrounding the light responsive switch means is below a selected level indicative of visually dark environmental conditions and energizes said electric powered means, thereby operating the windshield wiper means.

Abstract
An electrical control system for turning ON the headlights and taillights of a motor vehicle that has a first relay operable to turn the headlights and taillights ON when the ignition switch it turned ON. The first relay has a solenoid connected to the ignition switch and a pair of switches connected to the battery, headlights and taillights. A wiper control switch is connected to a second relay which turns the headlights and taillights ON when the windshield wipers are operating in the event of failure of the first relay or electrical circuit thereto.
