Abstract: The invention is a battery-powered light unit designed to be used as an emergency light or as a temporary replacement for one of a vehicle's tail or marker lights. The unit includes an array of light emitting diodes connected together on a circuit board. The board is attached to the unit using a quick-release connection. The rear surface of the unit includes two outwardly-extending magnets. The magnets are spaced apart by a predetermined distance so that the light unit can be placed on top of an existing light of a vehicle with the magnets contacting the metal body of the vehicle on either side of the light. This allows an operator of the vehicle to place the light unit over a non-functioning tail light or marker light without altering the appearance of the vehicle.

Abstract: In a temporary safety light replacement system a self contained individual safety light which is adapted to be secured as a replacement in close proximity to a broken safety light. The light has a self contained power supply and a recess switch which is not visually discernable and is protected from the elements when the safety light is secured to the vehicle. A special receptacle serves as a reflector when the receptacle is in its closed position and when moved to an open position secures two sides of the safety light to accomplish a strong positive attachment.
