  • Patent number: 5257172
    Abstract: A trouble light is provided which has an insulating housing and male prongs extending from one end of the housing and shielded by an extension of the housing. There is no conventional wired-in drop cord on the trouble light. Instead, an extension cord has a female socket and the aforesaid prongs on the housing are plugged into the extension cord female socket. A flexible retainer strap interconnects with the extension and is anchored on projections on the housing to prevent inadvertent disconnection of the extension cord from the trouble light.
