Abstract

An electric lamp, in particular a motor vehicle auxiliary light lamp, and a method for producing such a lam. The base of the lamp comprises an annular metal part (5) or resilient design for holding the lamp vessel (1), and a plastic part (6) provided with at least one hollow contact pin (7, 8). A supply lead (3, 4) projecting from the lamp vessel (1) is threaded into the hollow contact pin (7, 8) and welded to the latter such that the metal part (5) is under mechanical stress. In this way, backlash-free plug-and-socket connections are produced between the lamp vessel (1) and the metal part (5) or between the metal part (5) and the plastic part (6).
