This unique kit is sure to surprise all who see it! The kit shows a colorful Christmas tree which has 3 white looking bulbs (actually LEDs). When a 9V battery (not included) is connected, the bulbs on the tree blink all red then all green and then back to red again. The effect is magic! Size of PC board: 2 ½” x 2 5/8”. Circuitry uses 4 transistors to produce this unique display and a color label which you glue to the PC board before you start assembling the kit. Complete with all parts, label, PC board and instructions. Skill Level 1.
