    Abstract: A method and apparatus for shaping and redirecting a light beam in a light guiding media is described. The angle at which the light guiding media redirects the light beam is a variable predetermined value. A light beam is received at a first end of a light guiding media and redirected at an angle in relation to the angle at which the light beam is received. The light beam is transmitted through a second end of the light guiding media. The apparatus includes a light guiding media having an angular bend with an inner portion and an outer bend portion. The outer bend portion of the angular bend has a flat surface of the light guiding media having internal reflective properties. Another method and apparatus for spreading a light beam at a variable angle at a location is described in which a light guiding media is formed to shape and redirect a light beam.
