1. A device for compensating for cut-off line drift of a lamp in a vehicle, the device comprising:
an adjustment unit for adjusting the lighting direction of the lamp,
a carrier frame for carrying a lighting unit of the lamp,
a triangularly shaped connecting means mechanically connecting the adjustment unit with the carrier frame, the connecting means including:
a first joint at a first corner of the connecting means,
a second joint at a second corner of the connecting means,
a third joint at a third corner of the connecting means,
a first conjunction unit connected between the first joint and the second joint,
a second conjunction unit connected between the first joint and the third joint,
a third conjunction unit connected between the second joint and the third joint,
wherein the joints move the conjunction units relative to each other to compensate for cut-off line drift,
wherein the first conjunction unit and the second conjunction unit are each formed in one piece, and
wherein the third conjunction unit includes an extension means for extending the third conjunction unit linearly when the first conjunction unit, the second conjunction unit, and the third conjunction unit move relative to one another.
