Abstract
A photoluminescent member is provided for an exit device. The photoluminescent member comprises a housing member for mounting to the exterior surface of the exit device. The housing member includes a photoluminescent portion for being energized by exposure to an ambient light source and operable to automatically emit visible light photoluminescently for a substantial period of time in low ambient light or dark conditions and without being energized by an electrical current so that the photoluminescent portion provides illumination to identify the exit device in the low ambient light or dark conditions for providing a visual cue directing a person to a location of the exit device.
