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.
CAUTION: Forcing LEGO® to connect over a cable can result in damaging the cable and light.
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 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.
WARNING: Incorrectly inserting the connector can result in bent pins inside the port or possible overheating of the expansion board when connected.
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!
Instructions for installing this kit
1.) We will start by installing lights to the 2 lamps at the front door. Start by disconnecting the top sections of the castle so we can work with just the base. Remove the following lamp sections as per below.
You will require a LEGO Removal Tool to assist you in removing LEGO sections and creating gaps where required.
2.) Use the LEGO Removal Tool to lift and create a gap at the following position on the right side of the front door.
Remove the following sections
3.) Take one of the lamp sections and disassemble as per below
Take a White 30cm Bit Light and thread the connector side through the top (smaller hole) of the pearl gold round plate. Thread all the way through until the LED component of the Bit Light is right up against the bottom of the plate.
Reconnect the pearl gold plate back to the rest of the lamp ensuring the LED Component is clearly visible, then reconnect the remaining LEGO pieces to the lamp.
Reconnect the lamp with bit light installed back to the castle and then remove the right door.
4.) Thread the other end of the cable through to the inside of the castle and then lay the cable neatly underneath the gap we created. Reconnect the door to secure the cable in place.
Reconnect pieces we removed earlier and then close the gap by pushing down pieces together.
5.) Repeat step 2 to remove pieces and create another gap to the left side of the door.
6.) Repeat steps 3 and 4 to install another White 30cm Bit Light to the lamp on the right, then reconnect sections and push down on bricks to close up the gap.
7.) Turn the castle around so that we can access the inside and then pull the cables right through from the doorway.
Remove the following tiles from the base of the second floor and then remove the 6x8 plate from the middle, followed by the 2x10 plate behind.
Thread the 2 cables from front door up this space we have created and then set aside.
8.) Use the LEGO removal tool to lift and remove the middle section as per below.
Take a Strip Light and connect a 15cm connecting cable on each port (total 2x connecting cables). Since we are using several strip lights in this lighting kit, we will identify this one as striplight#1
Peel off the adhesive backing paper and to allow us to stick it to the base of balcony as close as possible to the 1x6 plate
Pull the connecting cables over before reconnecting the 2x10 brown plate and middle section we removed earlier
9.) Remove the following sections of the base of the second floor and then thread the connecting cable from the left port on striplight#1 underneath the 6x8 plate (but over the beam below) through to the left side.
Repeat this process for the right section and cable from the right port on striplight#1.
10.) We will now install lights to the chandelier. First remove this entire section at the 2x2 plate and then disassemble pieces as per below:
Take out 8 of the provided trans orange round plates which came in this set.
11.) Take a White 30cm Bit Light and then bend the LED component on a 90 degree angle with the component face up. Place the bit light inside one of the white round pieces and then secure by connecting a trans orange plate directly over it.
Repeat the above process to install another 7x White 30 Bit Lights using provided trans orange round plates to secure.
12.) Connect each light section back to the wheel ensuring each cable is facing toward the centre of the wheel.
Group all the cables together and then twist/wind them around each other so that they all come together to form one large cable.
Reconnect this section back to the roof of the ground floor.
13.) Bring the cables of the chandelier toward the front of the castle and then thread the cables up the space which leads to the second level. Lay the cables in between studs of the first brown brick before reconnecting the middle 6x8 plate directly over the top as well as the brown tiles we removed earlier.
14.) Take a 12-Port Expansion Board and then connect all lights from the chandelier as well as the 2 front door lights we installed at the start into available ports of the expansion board.
This is now a good time to test the lights we have installed so far. To do this take the USB Power Cable and connect it to your USB Power Bank. Connect the other end of the USB Power Cable into a spare port on the expansion board and turn on to confirm all the lights are working OK.
15.) Let’s move onto lighting the rest of the ground floor. Take a Strip Light (striplight#2) and then stick it onto a provided 1x6 plate. Connect a 5cm connecting cable into one of the ports. Take this strip light and connect the loose 15cm cable hanging from the left side of the roof into the spare port and then mount to the roof in the below position. Ensure the 5cm connecting cable is facing the right.
16.) Take another Strip Light (striplight#3) and stick to a 1x6 plate. Connect a 30cm connecting cable to one of the ports on the strip light. Take this strip light and connect the loose 15cm cable hanging from the right side of the roof into the spare port and mount to the roof in the below position. Ensure the 30cm connecting cable is facing the right.
Thread the other end of the 30cm cable up behind the back wall which leads up to the level above. Pull up from underneath and then connect the cable into one of the spare ports on the 12-port expansion board.
Take this time to test our lights we have installed so far by connecting back the USB Power Cable to the expansion board and verifying all is OK.
17.) We will now install lights to the 2 fire torches. First remove them and then disassemble pieces as per below:
Locate the provided 2x torch bases with Bit Light installed and connect your original 2x trans orange flame pieces over the top.
Reconnect these 2 sections back to the poles and then back to the pillars ensuring the cables are behind.
18.) We now need to thread the cable for each torch underneath the pillars at the below position.
To do this, use your LEGO removal tool to lift and create a gap opening to allow you to thread the bit light cable through the middle in between studs. Once threaded through close up the gap by reconnecting down the pillars.
Repeat this process for the torch cable on the other side.
19.) Take out one of the Flicker Effects Boards and connect the torch cables into the any 2 output ports as shown below:
20.) Locate the 5cm cable from striplight#2 hanging from the roof and connect this into the input port on the flicker effects board. Use 2x provided Adhesive Squares to mount the effects board to the top of the wall in the below position.
21.)We now need to eliminate excess cables from the 2 torches. To do this, bring the cables up and lay them underneath the grey tiles on the roof of the ground floor. You will need to first disconnect tiles, lay the cables in between studs, then reconnect the tiles over the top of them as shown below.
Test all the lights and effects are working together by connecting the USB Power Cable to the expansion board above. Turn on and verify all is OK.
22.) We will now move onto installing lights to each of the towers on the first floor. Remove the roof off the far left tower from the round white base as per below. Take a White 30cm Bit Light and stick underneath the white round plate in the below position using an adhesive square.
Reconnect this roof section back to the tower ensuring the cable for the bit light is laid over the grey bricks underneath toward the right.
Remove the roof off the next tower along and install another White 30cm Bit Light underneath the white round base using an adhesive square. Reconnect roof with cable in between the white round plate and grey brick underneath facing toward the centre.
23.) Repeat previous steps to install another 2x White 30cm Bit Lights for the two towers on the right side using adhesive squares(one bit light each).
You can use tape to neaten up and secure the cables to the sides of the tower.
24.) We will now install a light to the clock on the front. First remove the sections on each side of the front of the tower as per below.
From the back of the castle, use the LEGO removal tool to lift this section off at the following position.
Remove the clock piece as well as following pieces from the front.
25.) Take a White 30cm Bit Light and thread the connector side through one of the holes of the grey holes behind. Thread all the way through until you have about 5cm cable left. Stick the bit light to the following position using an adhesive square.
Reconnect the clock piece as well as other pieces we removed earlier.
Reconnect this whole section back to the castle and then reconnect the two sections on each side of the top.
26.) Take another 12-Port Expansion Board and connect a 5cm connecting cable to the first port. Connect the other end of the cable to the remaining port on the first expansion board.
Connect the Bit Light cables from the 4 towers as well as the clock light to the ports on the other side of the second expansion board.
Neaten up cabling by laying them down in between the centre section and walls of the castle. Tuck the expansion boards into the middle section as per below.
Test the lights we have installed again by connecting the USB Power Cable to the expansion board. Turn on to verify all is OK
27.) Take the Multi-Colour Changing Light String and connect it to the next spare port on the far right of the 12-port expansion board.
Lay the light string across the base of the second floor. Use 2x provided LEGO 1x2 plates to secure down at each side and do your best to ensure each of the 10 individual LEDs are facing up as we want them to shine as much as possible onto the front of the second level walls.
28.) Take a 30cm Connecting Cable as well as 2x 50cm Connecting Cables and connect them all into spare ports of the expansion board.
The 30cm connecting cable will be used to connect to lights on the second level of the tower. The 2x 50cm connecting cables will be used for the spot lights at the front of the castle which will shine on the front walls. Take the 50cm connecting cable connected to the left and neatly thread it toward the left side of the castle. Do the same for the other 50cm connecting cable, but thread it to the right side of the castle.
29.) Locate the following LEGO pieces which were provided in this kit and assemble them as per below to build 2x spotlights.
