<p>A signaling assembly is described and which includes a semi transparent mirror formed of a glass substrate formed of neodymium oxide doped glass and which absorbs, at least in part, a predetermined band of yellow light, and which further defines a region through which visible light may pass; and an emitter of visible light is positioned adjacent to the semi transparent mirror and which, when energized, emits visible light which passes through the region of the semi transparent mirror which passes visible light to form a visibly discernible signal.</p> |
