ABSTRACT:
The present invention relates to a protective cap for a motor vehicle headlamp and is intended to be mounted on the rear of a reflector (100) incorporated in the headlamp. The cap comprises an enveloping sleeve (20) which has inwardly projecting fastening means (21, 22) for co-operating with a rim (111) on the headlamp. The sleeve also has a flexible sealing lip (30) which rests, in use, against the reflector. According to the invention, the fastening means are arranged in a plurality of levels of generally annular structures projecting from the inside face of the sleeve and axially spaced along said inside face (23). In addition, the sealing lip is suitable for withstanding deformation including a radial component which is of the same order of magnitude as the axial separation between two adjacent levels of the projecting structures, while still providing proper sealing for the rear surface of the reflector (100).
