Abstract

An electrical circuit for an automobile. The circuit includes a battery, turn signal switch, brake switch, parking light switch, flashers, diodes, a relay, turn lights, parking lights, tail lights, and brake lights. When the turn signal is activated, the parking lights and tail lights come on. When the brakes are applied, the tail lights come on in the daytime and go off at night.

Claims

1. An electrical circuit for an automobile, said circuit comprising:

a battery;

a single-pole double-throw turn signal switch having a left turn position, a right turn position, and a center off position;

a first flasher and a second flasher;

a first diode and a second diode;

a single-pole single-throw relay having a normally open contact;

a third diode;

a single-pole double-throw brake switch having an off position and an on position;

a triple-pole single-throw parking light switch having a first normally open contact, a second normally open contact, and a normally closed contact;

front lights including a left turn light, a left parking light, a right parking light, and a right turn light;

rear lights including a left turn light, a left brake light, a left tail light, a middle brake light, a right tail light, a right brake light, and a right turn light;

and wiring connections between said components as follows;

said battery is connected through said turn signal switch and said flashers said front and rear turn lights;

said battery is connected through said relay to said parking lights;

said battery is connected through said turn signal switch, said first and second diodes, said relay, and said third diode to said tail lights;

said battery is connected through said parking light switch to said parking lights;

said battery is connected through said brake switch to said brake lights;

said battery is connected through said brake switch and said parking light switch to said tail lights.

2. The circuit of claim 1, wherein said circuit operates as follows:

When said turn signal switch is activated during the daytime, current flows from said battery to said normally open contact of said relay, allowing current to flow to said parking lights to turn said parking lights on, and also allowing current to flow through said third diode to said tail lights to turn said tail lights on;

When said turn signal switch is activated at night, the current flow is the same as during the daytime but there is no effect on said parking lights and said tail lights because said parking lights and said tail lights are already on;

When said brake switch is activated in the daytime, said parking light switch being off, current flows from said battery to said second normally open contact of said parking light switch and closes said contact, allowing current to flow to said tail lights to turn said tail lights on;

When said brake switch is activated at night, said parking light switch being on, said normally closed contact of said parking light switch opens, thus interrupting the flow of current from said battery to said tail lights to turn said tail lights off.
