ABSTRACT:
An electric, incandescent lamp including an electrically insulating (e.g., plastic) base which is securedly positioned on the lamp's sealed end portion without the need for adhesives or the like. The base functions to securedly retain the lamp's lead-in wires (a total of four in a dual filament lamp) in a preestablished alignment externally of the lamp's sealed end (from which the wires project) to thereby assure positive electrical connection thereto when the lamp and base are inserted within a corresponding electrical socket. The invention is ideally suited for use in a tail light assembly for an automobile.
