Vehicle windshield wiper light circuit
First Claim
1. An automatic windshield-wiper light circuit in a motor vehicle having headlights, tail lights, auxiliary lights and an electrical windshield wiper in electrically-operative circuitry with an electrical supply source comprising:
- an intermittent-current electrical line in electrical communication between a windshield-wiper switch and a windshield-wiper relay switch;
a multiple-speed electrical line in electrical communication between the windshield-wiper switch and the windshield-wiper relay switch;
rectifier circuitry in electrical communication between the intermittent-current electrical line and the multiple-speed electrical line.a diode rectifier in the rectifier circuitry;
an automatic light relay switch in current-communicative relationship between the windshield-wiper switch and select lights of the vehicle; and
an electrical circuit in communication between the lines to the windshield-wiper relay switch and the automatic light relay switch when the windshield wiper-switch is switched to electrical communication with the electrical supply source.

Abstract
Windshield wiper light circuitry for a device that automatically turns on vehicle head lights and other lights whenever the wipers are on is provided. A double-pole, single-throw relay switch (1) is positioned in vehicle circuitry between the ignition switch (13) and the light switch (14). One of the two poles has as electrical lead (3) to the low-beam head lights and the other (4) to the rear lights, park lights and side lights together. A diode rectifier (12) is provided in circuitry between a line (9) for continuous operation and a line (7) for intermittent operation of a wiper motor (11).
