Abstract
A vehicle light assembly includes a lens cover from which light emanates. A light shaping surface microstructure is carried in a portion of the light assembly. The microstructure can be incorporated into many different surfaces of the light assembly such as a surface of the lens cover, a surface of a macro-optical structure on the lens cover, or on a reflective surface of the assembly. The microstructure homogenizes and directs light emanating from the light assembly via reflection or transmission to provide a smooth, continuous pattern of light having a predetermined distribution shape or envelope and a predetermined directionality.
