TITLE: ELECTRIC LAMP WITH INSULATING BASE PROVIDING IMPROVED WIRE RETENTION An improved electric 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's) 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. This wire retention is possible by embedding each conductor within designated channels in the base and subsequent deformation of the base's material to substantially cover the embedded wire. In addition, a locking arrangement between the lamp envelope's press sealed end and the base is provided to assist in retaining the sealed end within an opening within the base. The invention is ideally suited for use in a tail light assembly for an automobile. |
