1. A system for controlling a lighting system for a vehicle comprising:
- an ambient light sensor operable for detecting a level of ambient light;
a lighting circuitry comprising at least one interior light;
a logical control unit operable for receiving one or more input signals from a vehicle control unit, a user input device and the ambient light sensor; and
wherein the logical control unit responsively controls a voltage on the lighting circuitry to provide a minimum voltage based on the one or more input signals, wherein the minimum voltage is a variable voltage level that is selected to ensure that the at least one interior light produces a sufficient amount of light such that an operator can operate the vehicle, while minimizing a power consumed by the lighting system, wherein the minimum voltage is proportional to the one or more input signals received from the ambient light sensor.

Abstract
A system for controlling a lighting system for a vehicle includes an ambient light sensor operable for detecting a level of ambient light and a lighting circuitry. The system also includes a logical control unit that receives input signals from a vehicle control unit, a user input device and the ambient light sensor. The logical control unit controls a voltage on the lighting circuitry to provide a minimum voltage based on the one or more input signals.
