The invention relates to a motor vehicle headlight having at least one first light source and a headlight lens which comprising, for example, a blank-molded integrally formed body which is made from a transparent material, and which comprises at least one light tunnel and a light-conducting part having at least one optically effective light exit surface, wherein the light tunnel comprises, an optically effective, light entry surface and merges, while forming a kink, into the light-conducting part for imaging the kink as a light-dark boundary by means of light coupled in or radiated into the light entry surface from the first light source, wherein the light tunnel has a transition region in which the surface delimiting the light tunnel at the top rises in the direction of the light-conducting part.
