Abstract
The headlight system has a pair of low beam and a pair of high beam lamps (1a, 1b; 2a, 2b) adapted to be mounted in the front part (3) of an automobile with one lamp of each pair to a respective side of the front part. The lamps each have a flattened concave reflector, a high-pressure discharge arc in a translucent envelope as a compact light source, and a substantially quadrangular lens. The ratio of width and height of the lens is larger than 3 and the height is smaller than 6 cm. The low-beam lamps produce a beam of uniform brightness, large width and length and sharp light darkness transitions, as a result of which the risk of dazzling is small despite a large viewing distance.
