Basic Brick-Built Traffic Light

Carefully remove your traffic light from its packaging. The packaging should include the two items shown in the photo:

One traffic light assembly with three wires pre-connected to a controller board (in protective shrink tubing, color may vary) with power cable

One BRANCH04/A4 adapter board with three standard-sized connecting plugs.

Note that the pre-mounted LEDs in the traffic light cannot be removed or installed in another traffic light design.

Do not disassemble the LEGO parts of the traffic light-- doing so may damage the LED wires and cause one or more sections of the traffic light to stop working.

The illustration in this step shows how to connect the traffic light to a power source (sold separately).

All plugs/connectors on the BRANCH04/A4 adapter board are electrically connected, so you can plug any wire into any connector.

Once power is turned on, the traffic light will begin its operating sequence of changing from green to yellow to red and back to green.

The timing of the transition from green to yellow to red is pre-set in the effect controller program and cannot be adjusted.
