16 bright flashing red LEDs! Easy 9V battery operation! Self standing or "hangable? Electronic kit, assembly required This LED Christmas Tree is a very neat looking self standing attention getter! The green PC board has 16 bright red LEDs mounted in the traditional tree pattern. A nice 4 transistor circuit is used to make the LEDs blink just like your big tree does! An attached battery pack mounts on the bottom allowing the tree to be self standing or to be hung on your tree. Runs on a standard 9V battery (not included).
