Abstract: An antidazzle headlamp has a reflector which is asymmetric relative to a horizontal plane passing through an optical axis of the reflector. The contours of the reflector corresponding to vertical sections in parallel planes forming right angles with a horizontal plane passing through the optical axis, form an upper and a lower half ellipse. Both half ellipses in each vertical section have a common large axis which is staggered upward relative to the horizontal plane. In this manner an antidazzle light beam is created which guarantees an intensive and complete illumination of edges of a roadway even at a close range from the motor vehicle.
