A discharge lamp and a headlight for a motor vehicle are proposed. A moving member is provided, which is movable between at least two positions, for switching over between different light distributions. It comprises at least one optically active element, preferably a lens, which generates an image of the gas discharge which is shifted away from the actual location thereof. A switch-over between two different light distributions is made possible by a movement of the moving member between the two positions in the headlight, such that the gas discharge seems to be shifted by the switch-over for a respective region of the reflector, whereby different light distributions are created. Preferably, the moving member is the outer bulb of the discharge lamp, on which two lenses are arranged and which is rotatable about the optical axis.
