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 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.) Start by removing the top sections of the back half of the Falcon as per below:
2.) Take 6x White Strip Lights and 6x 5cm Connecting Cables and then connect them all together. Leave one end of the connecting cables spare as shown below:
3.) Take the 12-port Expansion Board and connect the connecting cable with the spare end to the port furthest to the right.
4.) Disconnect the outer section of the back jets(left side) and then stick the first strip light (closest to the expansion board) down using it’s adhesive backing. Pull the cable and expansion board over the left side so that it is sitting inside the falcon then reconnect the outer section of the back jets(left side).
Reconnect the outer section of the back jets.
5.) Stick the second strip light (using it’s adhesive backing) to the section as per below image.
6.) Stick the third strip light to the same positions as in the below images. Note that we will only be sticking down about .5cm of the strip light.
7.) Disconnect the middle section of the back jets and then lay the cable that leads to the fourth strip light in between studs. Stick the fourth strip light in the below position (again using only .5cm of the left side of the strip light) and then reconnect the middle section to secure the cable in place.
8.) Stick the fifth and sixth strip lights down to the following positions ensuring you disconnect the back jet at the right side before sticking down the sixth strip light.
Reconnect the back jet at the right side.
9.) Take the AA Battery Pack and insert 3x AA batteries to it. Connect the battery pack cable to the 12-port expansion board and then turn the battery pack ON to test the lights for the back jets.
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.
Place the battery pack down underneath the expansion board and inside the back section of the inside of the falcon.
10.) We will now light the interior cabin section closest to the back. Start by disconnecting the corridor section to the left.
Take an Adhesive Square and stick it underneath this section. Take White 30cm Bit Light and stick it down to the adhesive square with the cable facing down as per below.
Reconnect this corridor section ensuring the cable is facing behind then pull the cable behind and then down the centre of the falcon.
11.) Disconnect the corridor section in the middle and then take an Adhesive Square and stick it underneath this section. Take a White 30cm Bit Light and stick it down to the adhesive square with the cable facing down as per below.
Reconnect this corridor section ensuring the cable is facing behind. Secure the cable by laying in between studs underneath the dark grey 2×2 plate.
12.) Remove the control panel section toward the right of the middle corridor and then disassemble this section as per below

Reconnect the middle section securely.
Turn the Battery Pack on(or USB Power) to test the lights we have installed to this cabin section.
30.) Take another 6-port Expansion Board and connect the other end of the 30cm connecting cable from step 28 to the first available port on the expansion board. Bring the expansion board over to the left
31.) We will now install lights to the front of the Millennium Falcon. First remove the front plate sections from each side as shown below.
Remove the following pieces from each plate.
Starting with the left plate, take a White 30cm Bit Light and place it directly over the stud shown below ensuring the cable is laid the same way. Take one of the provided 1×1 Round Plates (trans red) and connect it over the top securing the Bit Light in place.
Reconnect the remaining piece ensuring the cable is laid underneath and then reconnect this section back to the front left of the ship.
32.) Repeat the previous step for the front right side using another White 30cm Bit Light and provided 1×1 Round Plate (trans red)
33.) Pull the cable from the front left side across to the right toward the inside and secure it underneath the dark grey bar as shown below before connecting the Bit Light into the 6-port expansion board.
Secure the cable underneath the light grey tap pieces as shown below:
34.) Repeat this process for the front right side.
Turn on the Battery Pack(or USB Power) to test the front lights are working OK
35.) Take the remaining 30cm Connecting Cable and connect it to the 6-port expansion board. Leave the other end as is as we will connect this later.
Neatly place the expansion board in between sections as per below
36.) Remove the entire roof sections that leads to the cockpit.
Remove the cockpit window, as well as the section underneath.
Remove the right section of the cockpit as well as the following section underneath.
37.) Take the remaining White 30cm Bit Light and place it directly over the middle stud at the front ensuring the cable is facing out. Connect the provided 1×1 Round Plate (trans clear) over the top of the bit light, securing it in place.
Pull the bit light cable underneath the cockpit and secure it in the space in between the side and middle section.
28.) Take the section underneath the cockpit and then stick 2x adhesive squares in the following positions.
Take the 2x Blue 30cm Bit Lights and then stick them on the adhesive squares with cable facing the same way as shown below.
Reconnect the section underneath the cockpit and thread all cables underneath and then along the right side.
29.) Reconnect the section underneath the right section of the cockpit we removed earlier and then connect the lower section of the cockpit underneath securely.
Reconnect the right section of the cockpit ensuring all cables are neatly hidden underneath.
Reconnect the cockpit window.
30.) Group the 3x Bit Light cables together and then thread them underneath the white bar that leads inside the falcon. Take a 6-Port Expansion Board and then connect the bit light cables to available ports.
Locate the other end of the 30cm connecting cable from the expansion board earlier (step 35) and connect this to an available port.
Neatly place the expansion board inside the middle compartment and then turn the Battery Pack on (or USB Power) to test all lights are working so far.
31.) Reconnect corridor roof sections that lead to the cockpit as well as the front half roof sections of the ship ensuring all cables and components are neatly hidden underneath.
32.) We will now install lights for the top and bottom cannons. First remove the main round roof section above and then disconnect the cannon section at the technic blue pin.
Disassemble pieces from the 4 cannon sections as per below.
33.) Take one of the Red 30cm Bit Lights and thread the connector side through the top of the 1/2L technic pin. Thread the bit light all the way through and then bend the LED component slightly so that it sits flat against the top of the pin.
Take one of the provided Trans Red 1×1 Round Plate and connect it directly over the top of the Bit Light to secure it in place.
34.) Reconnect the 1/2L technic pin to the section below and then thread the bit light cable through the technic ring.
Bring the ring up and then reconnect it to the pole section ensuring you eliminate excess cable by pulling the end of the cable down as you bring the ring up.
Reconnect the dark grey 1×1 round brick underneath.
Repeat the previous 2 steps to install another Red 30cm Bit Light to another cannon.
35.) Reconnect the 2 cannons with lights to the cannon base. Connect one on the top left and the other on the bottom right ensuring the cables are facing the same way as per below.
Take the 2 cables and then wind them around each other from top to the bottom so they become one larger cable.
36.) Repeat steps 34 and 35 to install lights to the other 2 remaining top cannons using another 2x Red 30cm Bit Lights and provided Trans Red 1×1 Round Plates.
37.) Reconnect the 2 cannons with lights back to the cannon base (this time top right and bottom left) and then wind the 2 cables around each other just like we did for the previous 2 cables.
38.) Take 2x 6-Port Expansion Boards and 2x 5cm Connecting Cables. Connect a 5cm cable to each expansion board and then connect 2 bit lights from each cannon to each expansion board as shown below.
39.) Wind all the cables around each other from top to bottom forming one larger cable.
Take the round roof section, open the window and then thread the expansion boards and rest of the cable through the top. Thread the cable all the way through.
Before reconnecting the cannon section, disconnect one of the side pieces and then neatly place the large cable inside before reconnecting this section.
Note: if you decide that it is more visually appealing to leave the trans red pieces off, you can simply remove them so they look more like the original set.
40.) Place the upper cannon section on the roof of the falcon but do not reconnect it just yet.
Connect the ends of each 5cm cable from the each expansion board into each output port of the Multi Effects Board we connected in step 21.
42.) We now need to setup the chosen effect on the Multi Effects Board. First turn on the Battery Pack (or USB Power) and then set the switch on the multi effects board to the middle (we will be using the emergency effect to display as the shooting canon effect). Turn the effect dial all the way to the left for the slowest effect. You should now see the upper cannons firing away in sequence.
43.) We will now install lights to the cannons below the ship. First disconnect the canon section at the technic blue pin and then disassemble pieces from the 4 cannon sections as per below.
Repeat steps 32–37 to install another 4x Red 30cm Bit Lights to the 4 lower canons using the provided Trans Red 1×1 Round Plates.
Wind all the cables around each other from top to bottom forming one larger cable and then thread the cable into the space in the middle of the canon base.
44.) From the top of the Millennium Falcon use a long stick/straw/pen to push down to open the round LEGO glass piece then feed up from underneath the large cable of Bit Light cables.
Pull the cables up from the below opened window and then connect 2 of the cables to each 6-port expansion board. We need to ensure that 2 cables from the top left and bottom right cannons are connected to one expansion board and the other cables from the top right and bottom left cannons are connected to the other expansion board. Turn the battery pack on(or USB Power) to verify/adjust accordingly.
Reconnect the bottom cannons at the technic blue pin and pull up (from above) any excess cable before closing (pushing up) the LEGO glass piece.
Before reconnecting the main round roof section above, neatly tuck the expansion boards, effects board, and any excess cabling into the middle section.
This finally completes installation of your UCS Millennium Falcon Lighting Kit. Now turn ON your light kit and ENJOY!
