Abstract

Abstract A lamp for illuminating the rear license plate of a vehicle has a transparent plastics casing over which a plastics cover fits, two protuberances of the casing fitting into two apertures in the cover to provide the desired illumination. The cover has fixing pins which snap-engage in slidable blocks trapped behind the rear bumper of the vehicle to locate the lamp in a seat in the bumper. Respective metal contacts have integral blade connectors which project through the bottom of a plastics lampholder with which the casing is snap-engaged, to make contact with two lamp bulbs in the casing.

Claim 1
Independent Claim 249 words
A lamp assembly for illuminating the rear license plate of a motor vehicle comprising a transparent casing having a substantially rectangular box-shaped configuration adapted to be received in a complementary sized aperture in the bumper of a motor vehicle, said casing being open along one of the longitudinal sides thereof and having two spaced-apart protuberances extending outwardly from the surface of the opposite side and two apertured securing tabs extending outwardly from each end thereof, a lamp holder element having a substantially rectangular configuration disposed in said casing closing the open side of said casing, releasable interfitting engagement means for releasably connecting said lamp holder element to said casing, a cover member having a substantially rectangular configuration slightly larger than said casing and having a pair of spaced-apart apertures therein complementary in size to said protuberances, said cover being disposed in overlying engagement with said casing with the protuberances on said casing extending through said apertures, connecting means secured to opposite ends of said cover means and extending through said apertured tabs on said casing for securing said cover member and casing to said bumper, and a common metal contact strip having two tubular portions integral with opposite ends of said strip and adapted to receive and to make contact with the base of two separate bulbs, two mounting tabs integral with said tubular portions securing said strip to the lamp holder element and a central blade integral with said strip and projecting outwardly through said lamp holder element.
