Abstract
A vehicle lighting system includes a light source for generating light and a unitary optical element having a light collimating surface, a plurality of stepped surfaces projecting from the collimating surface, each stepped surface having a reflective surface angled with respect to the collimating surface for receiving collimated light, a dispersal surface angled with respect to the stepped surfaces, the dispersal surface having a plurality of dimples aligned with respect to the reflective surfaces for dispersing collimated light, and a kicker adjacent the surface having a plurality of reflective facets adapted to receive and redirect the dispersed light.
