Abstract

Abstract An auxiliary circuit adapted to be incorporated into the electrical wiring system of a motor driven vehicle is provided which automatically triggers the headlights to their lighted condition upon activation of the windshield wipers. The headlights are automatically turned off upon deactivation of the windshield wipers or placement of the ignition switch in the ''''off'''' position.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 122 words
In an electrical circuit for selectively controlling the energization of the headlights and the drive motor of the windshield wipers of a motor vehicle either simultaneously or independently of each other, the improvement comprising, first control means adapted to be energized for simultaneously establishing a first energizing circuit for the headlights and the windshield wipers drive motor, second control means adapted to be energized for establishing a second energizing circuit for the windshield wipers drive motor, said first control means including contact means connected in circuit with said second control means and being responsive to deenergization of said first control means to permit energization of said second control means to thereby establish an independent energizing circuit for the windshield wipers drive motor.
Claim 2
Dependent Claim 122 words
In an electrical circuit for selectively controlling the energization of the headlights and the drive motor of the windshield wipers of a motor vehicle either simultaneously or independently of each other, the improvement comprising, first control means adapted to be energized for simultaneously establishing a first energizing circuit for the headlights and the windshield wipers drive motor, second control means adapted to be energized for establishing a second energizing circuit for the windshield wipers drive motor, said first control means including contact means connected in circuit with said second control means and being responsive to deenergization of said first control means to permit energization of said second control means to thereby establish an independent energizing circuit for the windshield wipers drive motor.
Claim 3
Dependent Claim 54 words
In an electrical circuit as set forth in claim 1, wherein said second control means includes indicator means adapted to be energized upon energization of said second control means to alert the operator of the motor vehicle of the energization of the windshield wipers drive motor independently of the headlights of the motor vehicle.
Claim 4
Dependent Claim 31 words
In an electrical circuit as set forth in claim 1, further including a circuit means connected to bypass said first control means for establishing an independent energizing circuit to said headlights.
Claim 5
Dependent Claim 87 words
In an electrical circuit as set forth in claim 1, wherein said second control means includes a manually operable switch serially connected with said contact means to permit manual control of the energization of said second control means, said second control means further including first contact means and second contact means serially connected with said switch for establishing upon energization of said second control means said independent energizing circuit and an alarm circuit for alerting the motor vehicle operator of the establishment of said independent energizing circuit.
Claim 6
Dependent Claim 53 words
In an electrical circuit as set forth in claim 4, wherein said first control means includes a manually operable switch and a pair of contact means serially connected with said switch for simultaneously establishing upon energization of said first control means said energizing circuit for the headlights and the windshield wipers drive motor.
