Abstract
A house number light includes a frame defining an opening in a central portion and having a side opening along an inside face. The frame includes light sources, first and second power sources configured to provide electric power to the light sources, and a control circuit connected between the first power source and the light sources and connected between the second power source and the light sources. The control circuit electrically couples one of the first and the second power sources to the light sources at a time. If the first power source is electrically coupled to the light sources, electrical energy from the first power source passes through the control circuit to the light sources, and if the second power source is electrically coupled to the light sources, electrical energy provided by the second power source passes through the control circuit to the light sources.
