Vehicle light, windshield wiper control system
First Claim
1. An automatic system for controlling the turning on of vehicle headlights when any of the following switch combinations are turned on:
- a) ignition, windshield wiper, light sensor;
b) ignition, and windshield wiper;
c) ignition and light sensor;
and keeping them on as long as any of such switch combinations are on, comprising manual on-off switches for the ignition and windshield wiper and a condition responsive switch for the light sensor, a multistage digital logic circuit having a first stage which comprises a plurality of gates coupled to the outputs of said switches, at least one additional stage of gates connected to the outputs of said first stage of gates, a first relay circuit, an electronic relay switch, said relay switch having means for connecting said headlights to power supply means, said first relay circuit being alternately connectable to actuating means for said relay switch which governs the connection of said headlights to said power supply means, said power supply means connected to said first relay circuit, and control means for said first relay circuit, said multistage digital logic circuit connecting the outputs of said ignition, windshield wiper and light sensor switches to the control means for said first relay circuit.

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.
