ABSTRACT:
A simulated laser light system includes a light source which emits substantially parallel light rays and a prismatic element having a plurality of prismatic surfaces. The prismatic surfaces define a curved surface either on the inside or the outside of the prismatic element. The prismatic surfaces redirect the light rays emitted from the prismatic element in a plurality of planes which are perpendicular to a tangent to said curved surface. The simulated laser light system appears to emit light from a centerline of the prismatic element when the light is actually emitted from an exterior surface of the prismatic element.
