A bumper assembly that includes a molded bumper fascia and a molded cover/bezel mounted in an opening in the bumper. The bezel/cover is adapted to contain a fog lamp and is accurately positioned within the opening of the bumper fascia to avoid motion along the longitudinal axis of the opening, both in the forward and reverse directions, by external ribs on the cover/bezel that engage edges of the bumper to act as detents. Living hinges may be integrally molded with the bumper fascia to provide a mechanical fixation to the cover/bezel after the cover/bezel is installed in the opening and the hinges are bent from their mold positions.
