Abstract
An apparatus for providing a light signal to a signal unit at an overhead location along a railway signal structure, particularly a cantilever signal structure having a vertical mast and an arm assembly extending therefrom. Signal units may be located along the mast and/or the arm assembly. A light source is provided at or near ground level so as to be readily accessible by a maintainer and is connected by fiber optic cable to the signal units. Thus, light produced by the light source travels through the optical fiber to the signal units.
