ABSTRACT:
Apparatus for lighting a lower tread of a stairway having the lower tread relatively parallel to and spaced a gap from an upper tread. The lighting apparatus includes illuminating means. A housing is positioned underneath the upper tread. The housing includes an open front face generally perpendicular to and facing a front portion of the lower tread. The housing defines an interior region adapted to contain the illuminating means and includes a wall having an opening sized to receive therethrough the illuminating means. The lighting apparatus includes a louver angularly overhanging the open front face of the housing so that light diffused from the illuminating means is directed downwardly to illuminate the lower tread. The louver includes a tab removably insertable into a pocket partially defined by a surface of the upper tread and a generally plane wall of the housing. The tab secures the louver in the overhanging position after the tab is installed in the pocket.
