Abstract: The invention relates to a motor vehicle headlight lamp having a metal-plastic cap whose electric connections are constructed as contact lugs (16, 17). According to the invention, the two contact lugs (16, 17) in each case have a groove (16c, 17c) in which in each case a supply lead wire (12, 13) which is guided out of the lamp bulb is fixed to the corresponding contact lug (16, 17) by a welded joint. Furthermore, the contact lugs (16, 17) are equipped with means (16f, 17f) for threading the supply lead wires (12, 13) into the respective groove (16c, 17c) and the lamp cap has at least one cut-out (18) which serves the purpose of carrying out the welding of the supply lead wires (12, 13), arranged in the grooves (16c, 17c), to the contact lugs (16, 17).
