Abstract
The present invention pertains to paper product devices for holding toilet paper, particularly toilet roll spindles and holders that simultaneously provide illumination in an area. Embodiments described for the present invention use a toilet paper spindle housing, one or more springs designed to hold the electrical device in place, a power source, often battery powered, one or more lights within the housing to illuminate an area around and including a toilet, an ambient light sensor to detect an ambient light level, a toilet paper slide preventer and motion sensor guard, and one or more passive infrared sensors to detect movement in an area. The embodiment may illuminate an area for a specific time duration once motion or occupancy is detected. In one embodiment, the toilet roll spindle housing attaches vertically to a freestanding base and may be comprised of a power source, a photocell sensor, and infrared sensors.
