ABSTRACT:
A lighting subsystem is disclosed that uses optical devices to alter, the actual or apparent optical position of the ends of optical fibers coupled to a high intensity light source so as to provide all of the forward illumination needs for a vehicle. In one embodiment, optical wedges are interposed between a rectangular array of optical fibers and an array of lens elements mountable on the front of a vehicle from which the forward illumination is transmitted therefrom. The imposition of the optical devices alters the actual or apparent optical position of the fibers relative to the lenses and thereby changes the forward illumination from its low to its high beam pattern, to a fog beam illumination or to a cornering illumination pattern. In another embodiment, flat shaped optical members are rotated to provide the various forward illumination needs of the vehicle.
