Abstract
A vehicular lighting assembly (and methods of making the same) that includes a parabolic reflector; a translucent lens element; and a light source configured to emanate light that strikes an interior surface of the reflector and exits the assembly through the element. Further, an interior surface of the lens element comprises one or more fluted regions that are substantially invisible and configured to refract light from the source away from oncoming vehicles. In addition, the fluted region can be within, on, or integral with, the interior and/or exterior surfaces of the lens element in certain configurations.
