Abstract
Abstract The headlamp has a housing (10) to whose front edge there is a fastened a transparent cover (20) made of plastic. The cover (20) has a surrounding edge region (42) over whose front end it comes to bear against the housing (10). Formed, in a manner such that it surrounds the edge region (42) with clearance, on the cover (20) is an outer edge (46), the free end of which points counter to the assembly direction (17) of the cover (20), which outer edge is elastically deformable toward the edge region (42) and has a plurality of outwardly protruding lugs (48) distributed over the circumference of the cover (20). A wall (28), surrounding the outer edge (46), of the housing (10) has a plurality of recesses (32) which are distributed over its circumference and into which the lugs (48) are latched. The outer edge (46) thus forms a stable latching element and, in addition, causes the cover (20) to be highly rigid.
