A low profile night light adapted to be positioned in a substantially level plane atop a floor has cylindrical sidewalls and apertures formed in the sidewalls at regularly spaced intervals. At least one light source such as an incandescent or fluorescent light or a light-emitting diode is positioned in registration with at least one of the apertures so that the at least one light source illuminates a fan-shaped area of a floor. A circular area is illuminated if a light source is placed into registration with each aperture. The night light may be positioned under a bed or other item of furniture and may be battery operated or connected to a wall outlet by an elongate power cord. Unlike a conventional night light that illuminates only an area near an electrical wall outlet, the novel night light can be positioned anywhere on a floor where a tripping hazard might exist.
