Abstract: An electrically steerable solid state light apparatus is ideally suited for traffic controls. There exist many applications where a driver wishes limited viewing angles of traffic signals for safety, one example being left hand turn arrows. Current state of the art for solid state traffic signals involves the use of a mechanical louver to block the light from the unintended traffic lanes. This approach reduces the intensity of the light and customization of the viewing angle available to the DOT (Department of Transportation).
