Light up any fireplace with flickering LED lights with this wonderful unit. Kit contains 3 super bright flickering 1.8 mm 3 volt bulbs. Very easy to use. Powered by attached 3 volt DC coin cell holder. Includes switch combo for easy on/off. The Fire Kit is a combination of 3 LEDs: a flashing red, a flashing orange and a solid orange.
