The invention relates to a headlight for a vehicle, comprising a concave reflector and a lamp arranged within the reflector to reflect light from the lamp to create an illumination beam with a bright/dark boundary. The lamp comprises a transparent vessel including a longitudinal axis, at least a first and second filament arranged within the vessel. A baffle arranged proximate to the first filament, and comprising first and second upper side edges. The first filament is arranged above a plane including the upper side edges. A different plane is through the center of the first filament and is arranged perpendicular to the longitudinal axis. The upper side edges are arranged symmetrically to a baffle symmetry axis extending from the center of the first filament centrally between the upper side edges. The lamp is arranged within the reflector rotated around said longitudinal axis by a rotation angle of 2°-20°.
