Abstract: An illumination device is provided for a remote control unit having a plurality of keys which consists of a housing sized to receive a portion of the remote control unit inserted therein. A lamp is located on the housing and is positioned to shine a light upon the keys of the remote control unit. A battery is located within the housing and is electrically connected to the lamp for supplying power to the lamp. An on/off switch is located on the housing and is electrically connected between the lamp and the battery. A normally opened push button switch is located within the housing and is electrically connected between the battery and the on/off switch. When the remote control unit is inserted into the housing, it will close the push button switch. The on/off switch can be manually turned on to energize the lamp and shine the light upon the keys of the remote control unit allowing a person to operate the keys in a dark environment.
