The assembly of headlights involves sticking the rim of a thin mirror to the corresponding edge of a corresponding component. The cooperating sections (10, 20) - (30, 20) - (50, 60) are assembled by gluing. They are given shapes which define between them an expansion volume located inside the outer profile of the assembled components. The expansion volume is thus available to accommodate any possi...
