This traffic light effect board from Light my Bricks offers either 2 or 3 interchangeable light effects. It automatically changes colors from green, yellow, red (3-light option) or from green and red (2-light option). Choose between 3 light effects or 2 light effects with a press of the switch. Connect the power cable to a port and link the Bit Lights to the G-Port (green), Y-Port (yellow), and R-Port (red).

Please note: This effect board can only be used for the specified light effects. It cannot control the flashing or rotating Light my Bricks Bit Lights.

Power options: If you want to use 2 output connections for 2-6 Bit LEDs, the flat or round battery pack will suffice. If you wish to combine this effect board with more LEDs, expansion cards, and connection cables, you will need more power, such as from a AA battery pack or via a USB power cable.
