Description
Circuitry uses 4 transistors to produce a unique display and a color label to glue to the PC board before assembling. The kit shows a colorful Christmas tree with 3 LED bulbs. When a 9V battery (not included) is connected, the bulbs blink all red, then all green, and then back to red again.
