Abstract
A receiving assembly for a headlight range adjusting device for a lighting module in a headlight of a vehicle, with a receiving area for the headlight range adjusting device and with thermal compensator to compensate for a temperature-related displacement of a connection point for the lighting module in an adjustment axis of the headlight range adjusting device. The compensator has at least one profiled receiving area which extends in the adjustment axis and which is made of a first material with a first coefficient of thermal expansion, and the compensator has at least one receiving slide which extends in the adjustment axis and which is made of a second material with a second coefficient of thermal expansion, which is received in the profiled receiving area in the adjustment axis so as to be displaceable.
