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.
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
If you’re using the USB Power Cable, connect this to the board this instead of the battery pack, and connect the other end to a USB Power Bank or wall adaptor (sold separately) and turn it ON to test the front lights are working OK.
Disconnect the battery pack /usb 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.
Take the 6-port expansion board which is connected to the other end of the 30cm connecting cable and then push it through underneath the stairs behind the roller coaster platform
8.) We will now install lights underneath the front tracks. First disconnect the following double track section as per below then take out a Multi Colour Light String.
Thread the connector side of the light string underneath the platform through the left side. Pull it out from the left side behind the plat form and then connect it to a spare port on the 6–port expansion board we threaded through in the previous step.
Slightly disconnect the three front pillars at the bottom white round 2×2 brick as shown below:
9.) Lay the wire in between the 4th and 5th LED along the light string underneath the first pillar. Lay the wire in between studs, then secure it in place by pushing the pillar of white round bricks down over the top.
Continue to lay the light string underneath the next pillar of white round bricks in between the 5th and 6th LED on the light string. Secure the light string by pushing down the pillar over the top.
Slightly disconnect the next white pillar of white bricks, then lay the light string down underneath in between bricks. Lay the light string up towards the white pillar behind, then secure it by reconnecting the white pillar of round bricks.
Neatly lay the cable down toward the side of the light grey bricks as shown below:
10.) Pull the 6-port expansion board out from underneath behind the platform and then connect another Multi Colour Light String to the next port along.
Push all the components back underneath the platform until you can just see the second LED on the Light String
Disconnect the light grey tile along the back and lay the wire in between the 2nd and 3rd LED underneath in between studs. Reconnect the tile over the top
Lay the multi colour light string down underneath the first pillar in between the 4th and 5th LED, following the same method as we did for the first multi colour light string.
Continue to lay the light string underneath the next pillar, then again underneath the next pillar in between the 9th and 10th LED.
Bend the end of the light string down toward the front, then neaten up the two multi colour light strings by pushing the wires down along the side of the grey bricks as shown below.
