Programmable vehicle light controller
First Claim
1. A vehicle lighting system, for use in automobiles or trucks or other vehicles intended to be driven by a driver, where the vehicle has an electrical system incorporating an electric starter and a battery, comprising:
- a tail lamp;
a tail lamp relay having a control input, connected such that an electrical current flows through the battery, the tail lamp, and the tail lamp relay when the control input is in a first state, and current does not flow through the tail lamp when the control input is in a second state;
tail lamp switching means;
battery low voltage sensing means;
taillamp programming means;
means for sensing that the vehicle is in operation;
control means configured such that the control input of the tail lamp relay is in the first state whenever the vehicle is in operation and the tail lamp switching means is in a first state, or following the vehicle ceasing operation, the taillamp programming means is in a first state, and the battery low voltage sensing means senses a high battery voltage, but where the control input of the tail lamp relay is placed in the second state whenever the vehicle is not in operation and either the taillamp programming means is in a second state or the battery low voltage sensing means senses a low battery voltage.

Abstract
A vehicle lighting system, for use in automobiles or trucks has a tail lamp relay, connected so electrical current flows through the vehicle battery, a tail lamp, and the tail lamp relay when the relay is on; a tail lamp switch; a battery low voltage sensor; taillamp programming means; and means for sensing that the vehicle is in operation. The system also has control circuitry that turns on the relay in the first state when the vehicle is in operation and the tail lamp switch is on, or following the vehicle ceasing operation, the taillamp programming means is on, and the battery low voltage sensing means senses a high battery voltage, but where the relay is turned off when the vehicle is not in operation and either the taillamp programming means is off, the taillamp switch is off, or the battery low voltage sensing means senses a low battery voltage.

7. A vehicle light controller, for use as a component of the lighting system of vehicles including automobiles or trucks, where the vehicle has a headlamp system comprising high and low beam lamps, a high-low beam switch, and headlamp switching means, where the vehicle has tail lamps and tail lamp switching means, where the vehicle has electric windshield wipers and wiper switching means, and where the vehicle has an electrical system incorporating an electric starter and a battery, comprising:
-
a tail lamp battery input; a tail lamp output; a tail lamp relay having a control input, connected such that an electrical current flows between the tail lamp battery input to the tail lamp output when the control input is in a first state, and that current does not flow between the tail lamp battery input and the tail lamp output when the control input is in a second state; a tail lamp switching means input; battery low voltage sensing means; taillamp programming means; a vehicle in operation input; control means configured such that the control input of the tail lamp relay is in the first state whenever the vehicle is in operation and the tail lamp switching means input is in a first state, or following the vehicle ceasing operation, the taillamp programming means is in a first state, and the battery low voltage sensing means senses a high battery voltage, but where the control input of the tail lamp relay is placed in the second state whenever the vehicle is not in operation and either the taillamp programming means is in a second state or the battery low voltage sensing means senses a low battery voltage. - View Dependent Claims (8, 9, 10, 11, 12)
