Claim 1

A female electrical receptacle connected to an electric power extension cord, comprising an electrically insulating body having a side defining a generally planar surface for interfacing with a male plug, a "hot" terminal and a neutral terminal, an electrical resistor and an electrical lamp each having two terminals, the first terminal of the resistor being connected to the "hot" terminal, the second terminal of the resistor being connected to the first terminal of the lamp, the second terminal of the lamp being connected to the neutral terminal, a hollow cylindrical enclosure within said insulating body for accommodating said lamp and in which the hollow cylindrical enclosure is accessible only through an opening in the generally planar surface of the body, said opening being provided for access to said lamp for its removal and replacement thereof, the hollow cylindrical enclosure having on one side a window made of a transparent material whereby the lamp is visible from the outside, means for sealing said hollow enclosure including a cylindrical plug having a defined planar surface, said opening having female threads which engage male threads provided on said cylindrical plug whereby said hollow cylindrical enclosure is sealed by said cylindrical plug, the planar surface of said cylindrical plug being disposed in the same plane as that of said planar surface of said body, and said planar surface of said cylindrical plug further comprising slot means.
