Important things to note:
Laying cables in between and underneath bricks
Cables can fit in between and underneath LEGO® bricks, plates, and tiles providing they are laid correctly between the LEGO® studs. Do NOT forcefully join LEGO® together around cables; instead ensure they are laying comfortably in between each stud.
Connecting cable connectors to Expansion Boards
Take extra care when inserting connectors to ports of Expansion Boards. Connectors can be inserted only one way. With the expansion board facing up, look for the soldered “=” symbol on the left side of the port. The connector side with the wires exposed should be facing toward the soldered “=” symbol as you insert into the port. If a plug won’t fit easily into a port connector, do not force it.
Connecting cable connectors to Strip Lights
Take extra care when inserting connectors to ports on the Strip Lights. Connectors can be inserted only one way. With the Strip Light facing up, ensure the side of the connector with the wires exposed is facing down. If a plug won’t fit easily into a port connector, don’t force it. Doing so will damage the plug and the connector.
Connecting Micro Cable connectors to Micro Expansion Board Ports
Take extra care when inserting the micro connectors to micro ports of Micro Expansion Boards. Connecting Micro Bit Lights to Micro Expansion Boards is similar to connecting lights and cables to Strip Lights. With the expansion board facing up, ensure the side of the connector with the wires exposed is facing down. If a plug won’t fit easily into a port connector, do not force it. Use your fingernail to push the plastic part of the connector to the micro port.
Installing Bit Lights under LEGO® bricks and plates.
When installing Bit Lights under LEGO® pieces, ensure they are placed the correct way up (Yellow LED component exposed). You can either place them directly on top of LEGO® studs or in between.
OK, Let’s Begin!
1.) Lift up the bonnet, then remove the following sections in order for us to remove the two headlight sections as shown below.
2.) Take the right headlight section (passenger side) and disassemble it as per below, then take a Cool White 30cm Bit Light and thread the connector end of it through the front of the round dish. Thread the cable all the way through until the LED is about 1cm away from the front of the dish. Turn the LED over so that it is facing forward.
Take another Cool White 30cm Bit Light and thread it through the front of the dish, same way we did for the first light.
3.) Continue threading another 2x Cool White 30cm Bit Lights through the dish, then take LEGO Bar we removed earlier and insert it through the technic axle hole. Ensure the cables are laid in the technic axle spaces, to prevent them from being damaged when inserting the bar.
Reposition the 4 LEDs so they are evenly spaced out and positioned over the circles on the stickers behind, then reconnect the trans clear dish over the top. Reconnect the headlight to the rest of this section via the technic bar.
4.) Turn this section around and bring the 4 cables across to the right side underneath the technic pin. Bring this section over to the left side of the vehicle and thread the cables in between the two sections as shown below. Reconnect the headlight via the technic vertical axle.
Group the 4 cables together and thread them down the following space behind the front grill. Prop the vehicle up using your light kit box, then pull the cables down from underneath as shown below.
5.) Flip the vehicle over and thread the four cables through the following space underneath the technic bars, pulling them all the way out from the other side as shown below.
Turn the vehicle around to the side, and bring the cables back over and loop them around the wheel axis 3-4 times to eliminate excess cables, then connect them to the 12-Port Expansion Board
Take the AA Battery Pack and insert 3x new AA batteries to it. Connect the battery pack cable to a spare port on the 12-port expansion board then turn it ON to test the right headlights are working OK.
Note: If you experience any issues with the lights not working and suspect an issue with a component, please try a different port on the expansion board to verify where the fault lies (with the light, expansion board or effects board). To correct any issues with expansion board ports, please view the section addressing expansion board issues on our online troubleshooting guide.
6.) Take the following remaining head light sections and reassemble and connect them back to the front of the vehicle. Reconnect all the sections we disconnected earlier from the right side.
