Abstract
Abstract The light set comprises a plurality of strings of miniature lamps permanently joined in parallel circuit, each with respect to the others, at a pair of junctions which can be mounted at an upper portion of a Christmas tree. The string of lamps drape downwardly in free fall fashion at different radiant angles relative to the axis of the tree. The strings of lamps may comprise series connected or parallel converted lamps. The junctions of the strings of lamps are housed in an insulated casing which can be a socket connector to which a tree top lamp extension cord is disconnectably connected; or the tree top extension cord may be permanently connected to the parallel connected strings of lamps, at said junctions. A flasher lamp may be added in series with the series connected lamps of each string. The parallel connected lamps (of the strings of parallel connected lamps) may all be flasher lamps. Lead wires are permanently joined at said pair of junctions, and connect to a plug for insertion in a wall outlet. In light sets in which the strings of lamps comprise parallel connected lamps, the lead wires may also carry parallel connected lamps.
