Abstract
Abstract A light distribution system for an automotive vehicle is provided having a light source mounted in a fixed location in the vehicle. A plurality of light pipes is located in a fixed relation to said light source with each light pipe having a first and second end. The first ends each light pipe having a face which in combination substantially form a ring having a predetermined width with an outer diameter and an inner diameter. A collector for coupling light emitted by the light source into the first ends of the light pipes reflects the light on the faces of the light pipes in a ring-shaped pattern having a predetermined area.
