1. An incandescent lamp for rectilinear insertion into press-fit conducting relation with a conventional threaded electrical socket comprising:

  • a bulb having an axis, the bulb containing a filament and having a necked down trailing end;

    first conductor means connected to one end of the filament and mounted to the necked down trailing end of the bulb, said first conductor means comprising a plurality of axially extending, rearwardly directed, and outwardly radially biased resilient conductive fingers with memory, each finger being initially resiliently biased a predetermined radial distance from the axis of the bulb to form an initial composite diameter greater than the diameter of said threaded socket;

    second conductor means carried in exposed relation at the trailing end of the bulb and connected to the other end of the filament; and

    electrical insulating means disposed between the first and second conductor means;

    whereby the resilient fingers are inwardly deflected reducing said composite diameter to one equal to the socket diameter upon rectilinear insertion of the trailing end of the lamp into the socket, the memory of the resilient fingers insuring electrical conduction with a conductor at the socket threads.
