| has gloss | eng: A trouble light is a special lamp used to illuminate obscure places and able to handle moderate abuse. The light bulb is housed in a protective cage and a handle that are molded to form a single unit. It has a long power line for distant reaching; doubling as an extension cord, the power cord often has an electrical outlet at the end of it. The patent for the trouble light was filed on August 15, 1979 and published on June 23, 1981, by Harry M. Dorn. The patent is for A trouble light comprising a reflector, a cage and a handle all made of synthetic resin polymer, in which at least a part of the handle and either the reflector or the cage are molded as an integral unit. Trouble lights are usually powered by AC wall current, but some are powered by a 12-volt source, such as a car battery. The bulb of the trouble light typically has a heavy filament to withstand dropping. It is also referred to as a drop light. |
