Abstract
Abstract A lighting system for stair treads, risers and the interface of one with the other which can extend the full width of the step is disclosed. The system which employs fiber optics to give the needed safety information, is intended primarily for theatres, moviehouses, auditoriums and other darkened areas. The system can also be equally well employed in banisters and hand rails for both interior and exterior use.
