The system includes a controller that controls the color and intensity of interior lighting, a selector control that switches color and intensity controls to various groups of interior lights (such as instrument lights, indicator light), a color that controls light color and an intensity control that controls light intensity. In practice the controller is a microcontroller, the lights are tri-color light emitting diodes, the selector control is a multi-position switch, and the color and intensity controls are potentiometers. ## Claims ### Claim 1 A vehicle interior lighting system, comprising: a controller; a selector control applying a user adjustable selector input to said controller; a color control applying a user adjustable color input to said controller; an intensity control applying a user adjustable intensity input to said controller;
