Abstract

An electrical system is provided in a motor vehicle to activate the headlights and taillights once the windshield wipers have been switched on. The electrical system also provides for the headlights and taillights to be deactivated once the ignition switch is off. At least one relay is placed between the windshield wiper switch and the headlights and taillights. A current entering the relays from the initiation of the windshield wiper switch, induces a magnetic field across the inductor, closing the switches within the relays, thus illuminating the lights. If two relays are used, then the second relay maintains the activation of the headlights and taillights if the windshield wiper switch is deactivated. If the lights (headlights and taillights) are not desired then a push button switch can deactivate the lights.

Dependent claims

A safety device that is adapted to be connected with taillights, headlights, a windshield wiper motor, and a windshield wiper switch of a motor vehicle comprising in combination:

a first molded relay housing a first coil coupled to a first switch;
a male plug assembly is connected to said first molded relay;
said male plug assembly having first male extending means;
a female plug assembly having first female receiving means and is electrically and mechanically connected to said male plug assembly via a first wiring line;
a first circuit line has a first end that extends outwardly from said male plug assembly and a second end of said first circuit line is in electrical communication with a first end of said coil;
a second circuit line has a first end that extends outwardly from said male plug assembly and a second end of said second circuit line is in electrical communication with a second end of said coil via a second electrical communication means;
a third circuit line has a first end that extends outwardly from said male plug assembly or said female plug assembly and a second end of said third circuit line is coupled to a fourth circuit line;
said fourth circuit line has a first end that is coupled to said third circuit line and a second end of said fourth circuit line is coupled to said switch for enabling current to flow through said fourth circuit line when said switch is closed;
said male extending means is electrically connected to said fourth circuit line;
and
wherein said safety device is adapted to be inserted into said motor vehicle by enabling said first circuit line to be connected to a windshield wiper motor or said windshield wiper switch such that said windshield wiper switch is grounded when said windshield wiper switch is closed, said second circuit line is adapted to be connected in series with an ignition switch, said third circuit line is adapted to be connected to said taillights, said female plug assemble is adapted to receive a male end of a driver's side headlight, said male plug assembly is adapted to receive a conventional plug of said driver's side headlight of said motor vehicle, and said headlights and said taillights will be activated once said windshield wiper switch is activated.
