Abstract: A light assembly having a housing and an opening into an interior recess in the housing and a cover for covering the opening into the recess. The bottom wall of the recess has a lens construction integrally formed therein, such as by making the housing, particularly the bottom wall thereof, transparent to light. The inside wall surface of the cover has a U-shaped reflector mounted thereon, which U-shaped reflector has plural light bulbs spaced along the length thereof. The U-shaped reflector opens outwardly in a direction so as to face the transparent portion of the bottom wall of the recess. A labyrinth seal formed solely by the material of the housing and the material of the cover encircles the opening into the recess so as to make it unnecessary to provide a separate seal or gasket-like member.

Abstract: An adapter for facilitating a mounting of one or more wheels on a vehicle wheel hub having plural externally threaded wheel studs of a finite length secured thereon. The adapter has a cylindrical adapter body with plural parallel holes extending therethrough, each of the plural holes being adapted to receive in one end thereof an externally threaded wheel stud. An elongated bolt is snugly received in an end of each of the plural holes remote from the one end, each bolt having an enlarged head intermediate its length and engaging a shoulder on the adapter. An internally threaded opening is provided at one end and is adapted to be threadedly coupled to the wheel stud. An externally threaded stud is provided at the other end. Each bolt further has a recess therein intermediate the one end and the enlarged head. A barrier is fixedly and removably received in the recess.
