A night light device provides a low level illumination using electro- luminescent lighting (30D) which is automatically fumed on when motion near the device is detected by the device and if ambient lighting lev el is low. When the ambient light level is above a specified level so that it is possible to see without artificial light, the device is inactive. A high intensity lighting feature (30F) allows the device to be used as a flashlight in emergencies since the device is fastened to a wall in such a way that it is easily and quickly removed. The front face (10A) of the device provides a downwardly directed surface (10A-1 ) for projecting light toward the floor, and sideways directed surfaces (10A-2, 10A-3) for projecting light to each side. Spherical Fresnel lenses (30B-1) enable the device to detect motion over a 180 degree azimuth. The case (10) of the device may have phosphorescent doping s o as to provide a dim illumination even when the device is not energized.
