This season let your holiday designs glow with the warmth of incandescent mini Christmas lights. White sockets, white wire, and the 4-inch spacing make this string of 20 clear bulbs ideal for wrapping topiaries, centerpieces, and miniature trees. UL listed for indoor/outdoor use, the sets average 3,000 hours of trouble free lighting. The 8-foot set has a stackable male only connection so you can combine up to 21 sets, and the 18-inch lead makes reaching the plug easy. Decorate your home with bright and festive lights this holiday season.
