An electric lamp, in particular for motor vehicles, has a base with a connection area (14) made of an electrically insulating material and provided with the electric connections (15) of the lamp. The feeding lines (11) that lead out of the lamp bulb (10) are soldered in the inner cavity (18) of the connection area (14) to electric connections designed as contact lugs (15). The base is made gas-tight by one or several shaped parts (19) made of a heat-resistant, elastic material press fitted on the wall that delimits the inner cavity (18) and on the feeding lines (11) that lead through the shaped part(s) (19). Press fitting is ensured by the contact lugs-(15), which exercise a pressure on the shaped part(s) (19).

Cette lampe électrique, notamment pour véhicules à moteur, comprend une base avec une zone de raccordement (14) en un matériau électriquement isolant, pourvue de connexions électriques (15). Les amenées de courant (11) qui sortent de l'ampoule (10) sont soudées à des raccordements électriques en forme de cosses de contact (15) dans une cavité intérieure (18) de la zone de raccordement (14). Afin d'assurer l'étanchéité aux gaz, la base comprend une ou plusieurs pièces moulées (19) en un matériau élastique résistant à la chaleur, ajustées serrées sur la paroi qui délimite la cavité intérieure (18) et sur les amenées de courant (11) qui traversent la ou les pièces moulées (19). L'ajustage serré est établi par les cosses de contact (15) qui exercent une pression sur la ou les pièces moulées (19).
