This Kurt Adler 10-Light Clip-On Candle Light Set is a beautiful, festive way to add to the lighting of your holiday decor. Each of the 10 candle lights in this set features a clip design so that, when attached to the branches of your Christmas tree, they stand straight up. Each candle measures about 3.5 in height. Each indoor-only light set has clear bulbs, 12 spacing, a 30 lead wire, 4 spare bulbs, 1 spare fuse, and a 12V 0.08 amp replacement bulb R0042/C.
