    摘要: A headlight for a vehicle for producing a low beam and at least one light beam with a greater distance, the headlight comprising a light source, a reflector, the light source and the reflector together forming a headlight unit, an electrically adjusting device for changing a relative position between the light source and the reflector, a light width adjusting device for turning the headlight insert about an at least approximately horizontally extending axis, and a safety device operative for monitoring at least indirectly an operation of the adjusting device and in the case of an error when the adjusting device operates not in an orderly manner, the safety device reduces an electric power with which the light source is operated and/or reduces a distance of a light beam produced by the headlight unit.
