    • 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.

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

    • The traffic light includes two operating modes:

      • In the default mode, the traffic light operates as lights to in the United States: green to yellow to red and back to green.

      • In European mode, the traffic light operates in a mode common to many European countries: green to yellow to red to red + yellow and back to green.

    • To switch operating modes, touch a metal object to the two exposed gold tabs on the effect controller as shown in the photo, and release.

    • The yellow light will flash either fast or slowly to indicate the operating mode has been changed.

    • To switch modes back to the previous setting, touch both tabs with a metal object once again.

    • The mode setting is preserved even when power to the traffic light is turned off.

    • We hope you enjoy using the traffic light as much as we enjoyed designing it for you!
