Abstract: A light controller capable of varying the brightness of a light emitting diode in a linear manner. The light controller may control a number of lights in a predetermined pattern or in a pattern designed by the user. A remote control may be used to control and interact with the light controller. The light controller may have inputs for audio signals, tachometer signals, or other external signals. The light controller may be coupled to other light controllers to enable the control of additional lights in a synchronized manner. The light controller may be particularly well suited to controlling light emitting diodes and controlling lights in a vehicle accent lighting application, although many other uses may be apparent.
