An apparatus in the form of a stair nosing formation that is particularly adapted to provide an overhang for housing an indirect lighting source thereby to provide both functional and aesthetically appealing effects. The formation consists of a tread plate in perpendicular affixure to a riser plate while extending an overhang portion that is further formed into an overhang plate disposed parallel to the riser plate. A transverse plate is formed to extend between the overhang plate and riser plate to provide high structural strength while also defining a downwardly oriented channel for retention of an illumination source for directing light downward along the adjacent step riser toward the next lower step tread. |
