Abstract
A vehicle lighting system for a vehicle includes an accessory module assembly that is adapted for attachment to an interior portion of a vehicle and configured to illuminate, for example, an area inside the vehicle. The module assembly includes a single high-intensity power light emitting diode that has a luminous efficiency of at least about 1 lumen per watt when the light emitting diode is operated and is preferably operated at a forward current of at least 100 milliamps. The system also includes a voltage conversion element for converting the battery/ignition voltage of the vehicle to the forward operating voltage of the light emitting diode.
