A light fixture housing extrusion that includes a horizontal step plate intersecting a vertical riser plate and having first and second channels for mounting string light fixtures beneath removable translucent covers, the channels including grooved wall structures to facilitate securing of the covers and either a pair of tangs or a pair of interior recessed walls for receiving and retaining a spring-biased wedge clip lamp carriage. Other features include an improved wiring scheme with individually-fused light strings, a diode for dimming the light output of selected strings, and a riser lens cover having a unitarily-extruded extended shield which prevents viewing the direct glare from elevated lighting fixtures. An alternative glare reduction is provided by an opaque lens cover located directly above one or more lamps, the lens cover being mounted in a translucent extrusion structure, which mutes the lamp light, thus providing muted illumination on either side of the opaque lens cover. Edge and corner molding members for conformably mating with dual channel extrusion units and guiding electrical leads down the side of a staircase in concealed wire way channels are further provided.
