A rear lighting system includes an elongated light source emitting light and a solid lens having an inner surface comprised of a hyperbolic cylinder, said hyperbolic cylinder having a first focal line and a second focal line and a cylinder length. The first focal line is coincident with the light source and the outer surface is comprised of a generally planar shape perpendicular to the horizontal plane and the vertical plane.
