US Patent 9651211 Multi-function optical system with shared exit optic

A light for a vehicle. Two or more light guides each project a sheet of light to a common projection lens, but in different directions. Each light guide is selectively actuable by the driver. The projection lens receives the sheets of light, expands them in the horizontal direction, and projects them in the same general direction as received. Thus, the driver can selectively illuminate various regions of the terrain.
