ABSTRACT:
A miniature light set comprises lamps, lamp bases, lamp holders and a ribbon cord with three or more wires. Each of the lamp holders has a socket at one end which receives a lamp base and a wireway at the opposite end. The wireway has two upstanding elongate walls which define an elongate channel therebetween for receiving the ribbon cord, and has a transverse pressing bar at each end of the channel. Mounted on the outside of each wireway wall is an engagement lug. A pair of conductor plates are positioned in a bulb socket into which a lamp can be inserted with the lamp lead wires in contact with the plates. The other ends of the conductor plates project into the wireway and make contact with conductors in corresponding stripped portions of the wires. A snap-on cover has a base and two depending U-shaped sides that can engage the lugs and lock the cover on the wireway. On the underside of the cover base are two press bars and two press bits which are located between the lampholder pressing bars when the cover is installed. The location of the press bits correspond to the location of the conductor plates. With the engagement of the snap-on cover on the lampholder, the cord is bent and retained by the pressing bars of the snap-on cover and the pressing bars of the wireway.
