Abstract
A signaling assembly is disclosed and which includes a reflective substrate having opposite first and second surfaces, and wherein the reflective substrate simultaneously reflects visibly discernible electromagnetic radiation, and passes visibly discernible electromagnetic radiation; a plurality of electromagnetic radiation emitters which are borne by the second surface and which, when energized, emit electromagnetic radiation; and a reflector is borne by the second surface and which directs the electromagnetic radiation emitted by some of the electromagnetic radiation emitters in a direction so that it may pass through the reflective substrate and be viewed from a location forward of the first surface, and the electromagnetic radiation emitted by a remainder of the electromagnetic radiation emitters in a direction so that it may be viewed from a location forward of the second surface.
