Abstract
A fiber optic light guide for a vehicle lighting system has a light transmissive core and a light absorptive cladding provided circumferentially about the core. The light guide has a pair of end portions with opposing canted parallel end surfaces. The end surfaces are canted at a predetermined angle greater than the critical angle associated with the light transmissive core material and the surrounding air, so that if the end surfaces are separated light will not be emitted from the fiber optic light guide, but rather reflected off an end surface and into the light absorptive cladding.
