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.
