1. A headlight for a vehicle, comprising:a concave reflector and a lamp arranged within the aid reflector to reflect light from the lamp to create an illumination beam with a bright/dark boundary,
the lamp comprising
a transparent vessel including a longitudinal axis,
at least a first and a second filament arranged within the vessel,
a baffle arranged proximate to the first filament, characterized by
the baffle comprising first and second upper side edges, the first filament being arranged above a first plane including the upper side edges,
wherein in a second plane through a center of the first filament, the second plane being 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 being arranged within the reflector rotated around the longitudinal axis by a rotation angle of 2°-20°.
