ABSTRACT:
A light assembly for a motor vehicle includes a light source and a parabolic reflector for reflecting light emanating from the light source in the longitudinal direction of the vehicle. A lens is included in the light assembly. The lens is made from a transparent material and is positioned to produce total internal reflection of a portion of the light emanating from the light source and parabolic reflector. The totally internally reflected light rays are projected in a direction transverse to the motor vehicle. This enables a single light assembly to satisfy safety requirements pertaining to light projection both in the longitudinal direction of a vehicle and in its transverse direction.
