Abstract

The invention relates to a mounting system (12) for attaching and adjusting a vehicle light (10) on a motor vehicle. According to the invention, the mounting system (12) comprises a threaded sleeve, which is screwed into the vehicle light (10). A washer (28) is enclosed in the inner lateral surface (24) of the threaded sleeve and can be rotationally moved about the longitudinal axis (L) of the threaded sleeve. The washer (28) has, in the middle of same, a borehole through which a fastening screw (36) can be guided and can be locked by means of a fastening nut. The fastening nut has an interface by means of which the fastening bolt can be fastened to a vehicle structure (16). As long as the fastening screw (36) has not yet been tightly screwed with the fastening nut, the washer (28) can still be displaced between the fastening screw (36) and the fastening nut. The vehicle light (10) can thus be transversally positioned in a plane, wherein the plane corresponds to a support plane of the fastening nut on the directly adjacent vehicle structure (16). In the target position, the fastening screw (36) can be tightened, causing the washer (28) to be fixed. Now, only a rotational relative movement between the threaded sleeve and the washer (28) is possible, as a result of which the vehicle light (10) can still be adjusted along the longitudinal axis (L) of the threaded sleeve.
