Abstract: The assembly includes a grille, a lamp housing (reflector) containing a lamp socket, and a lens. These parts are releasably attachable to each other by a pair of flexible tabs which project upwardly from the lens at opposite sides thereof, and by a pair of rigid tabs which project upwardly from opposite sides of an external flange which surrounds the lower end of the reflector. The lamp housing extends upwardly through a central opening in the grille, and the flange on its lower end engages the underside of an internal flange formed on the grille around its central opening. The rigid tabs on the lamp housing overlie the flange on the grille to secure the housing to the grille, and the flexible tabs on the lens extend through registering notches in the housing and grille flanges, and have hook-shaped upper ends which overlie the grille flange releasably to secure the lens beneath the reflector.
