ABSTRACT:
An auxiliary lighting system contains at least one photoelectric cell to convert ambient light into energy and at least one light emitting diode. The photoelectric cell converts ambient light into energy which is stored in a storage cell. A switching system provides energy from the storage cell to the light emitting diode upon certain conditions, generally by time or by lack of ambient light.
