Abstract
An adjusting device for headlights which has adjustment means for adjusting a light distribution having a cut-off line to a predetermined position. The headlight has a matrix of semi-conductor-based light sources and an optical unit arranged in the main direction of the beam in front of the light sources for reproducing the light sources as a number of adjacent light spots which form the light distribution. First adjustment means are provided for aligning a vertical cut-off line of the light distribution in a vertical reference line on a screen arranged at a distance from the headlight. Second adjustment means are provided so that the vertical cut-off line of the light distribution can be displaced by a horizontal adjustment path, which is smaller than a horizontal width of a light spot limiting the vertical cut-off line.
