Abstract
A vehicular lighting assembly (and methods of making the same) that includes a parabolic reflector; a condenser lens comprising a non-planar rear surface; an outer lens; a bezel between the lenses; and a light source that emanates light that strikes the reflector and exits the assembly through the condenser lens and the outer lens. Further, the non-planar rear surface of the condenser lens refracts ambient light entering the condenser lens away from the bezel. In embodiments, the non-planar rear surface can comprise a convex or a concave surface.
