Abstract

A lamp socket for an electric lamp, in particular, for a motor vehicle headlamp with a plastic socket part is disclosed, with a first section made from a higher meting plastic in a region adjacent to the lamp bulb and a second section made from a lower melting plastic in a region of mechanical stress. Savings can thus be made in cost-intensive higher melting plastics whilst at the same time guaranteeing a longer service life in the region of mechanical stress.
