Make a dramatic lighting display this holiday with over-sized multi-color LED Christmas lights that change colors. The 15 cone-shaped bulbs are spaced 12 inches apart over 15 feet of green wire. The 4-pattern controller can be set to fade, chase, twinkle, or a combination of all. UL listed for indoor and outdoor use, 30 sets can safely be combined end-to-end. Ten times more energy efficient than incandescent, these oversized lights will make your holiday lighting a Symphony of Lights.
