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.




CAUTION: Forcing LEGO® to connect over a cable can result in damaging the cable and light.

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.



Incorrectly inserting the connector can can result in bent pins inside the port or possible overheating of the expansion board when connected.

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.



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.) The first thing we will light will be the ticket booth. Start by carefully disconnecting this section and then remove the front ‘Ticket’ sign and disconnect the four trans round tiles from it.









Disconnect the following side sections on the left and right of the Ticket sign and then disconnect the trans round tiles from each side.






2.) Take a Flashing White 15cm Bit Light and place it directly over the far left stud on the left side section. Secure it in place by connecting a provided LEGO Trans Yellow Round Plate 1×1 over the top.



Reconnect this side section back to the top of the ticket booth ensuring the cable is laid toward the centre as per below.


Take another Flashing White 15cm Bit Light and install it to the right side section, securing it in place with a provided LEGO Trans Green Round Plate 1×1.




Reconnect the right section to the top of the ticket booth ensuring the cable is laid toward the centre as per below (toward the left)


To make it easier to install the rest of the lights to the ticket booth, disconnect the roof.



3.) Take another Flashing White 15cm Bit Light and place it over the far left stud of the Ticket sign with the cable facing down. Secure it in place using a provided LEGO Trans Green Round Plate 1×1



Install another Flashing White 15cm Bit Light to the next stud along, securing it in place using a provided LEGO Trans Yellow Round Plate 1×1.



Install another 2x Flashing White 15cm Bit Lights to the next two studs, securing them using another provided Trans Green and Trans Yellow Round Plates 1×1.


4.) Fold the four cables underneath the Ticket sign and then hold the cables in place at the top of the back of the sign. This will allow us to reconnect the sign to the roof ensuring the cables are laid in between studs.





The two centre cables should be laid together in between studs.

Group all the cables together and then twist them around each other all the way to the top to form one larger cable





5.) Take an 8-Port Expansion Board and then connect all six cables to it



Test the flashing lights we have installed by taking the AA Battery Pack and inserting 3x AA Batteries to it. Connect the battery pack cable to a spare port on the expansion board and then turn it ON to verify the flashing lights are working OK



Disconnect the battery pack cable from the expansion board and then reconnect the roof to the ticket booth.


Take a 30cm Connecting Cable and connect one end to a spare port on the 8-port expansion board and then connect the other end to a 6-Port Expansion Board



6.) Reconnect the ticket booth back to the roller coaster base, then disconnect the two dark blue tiles on the right of the roof.



Lay the thick cable in between white studs as shown below before reconnecting the dark blue tiles over the top.



Reconnect the roller coaster track and then ensure all cables are pushed down and laying as flat as possible to prevent the roller coaster carriage wheels from getting stuck as it passes.


7.) Take 2x Adhesive Squares and stick them on the base side of the 8-port Expansion Board. Bring the cable over to the right and then mount the 8-port expansion board on the back of the front Roller Coaster pillar as per below.
