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.
