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.

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.) We will first start by installing lights to the Flying Ford. First remove the vehicle from the tree and disconnect the following sections from the top and front, then disconnect the headlight sections as per below.

2.) Disconnect the trans yellow round plates, then take a White 15cm Bit Light and thread the connector end through the front of one of the light blue bricks. Pull the cable all the way out from the other side, then carefully bend the Bit Light on a 90 degree angle so that it sits flat against the front side of the brick. Secure the Bit Light in place by reconnecting the trans yellow round plate over the top.

Repeat this step to install another White 15cm Bit Light to the other headlight, then reconnect both sections to the front of the flying ford.

3.) Lay both cables up the sides of the car in between studs before reconnecting sections we removed earlier.

Take the Micro Battery Pack (or 8-Port Expansion Board w/ 50cm Connecting Cable, if your Light Kit did not come with a Battery Pack) and remove the clear protection tag which sits in between the metal contact and batteries. Connect the two headlight cables to the ports, then switch the battery pack ON to test the headlights are working OK. Important Note: The Micro Battery Pack to power the car has been removed as of June 2022 due to child safety regulations. Please use the 50cm Connecting Cable and 8-Port Expansion Board in place of the Battery Pack to tether off the expansion board at step 34.

5.) Disassemble the left tail light section, then take a White 15cm Bit Light and with the cable facing down, place it over the front side of the dark grey stud. Secure it in place by reconnecting the trans red round plate over the top.

Fold the cable underneath this section toward the right side before reconnecting it to the grey 1×2 plate.

Repeat this step to install another White 15cm Bit Light to the right tail light except this time, fold the cable down underneath it toward the left side as shown below:

6.) Reconnect both tail light sections to the back of the vehicle, then reconnect the two ‘L’ shaped tiles ensuring the cables are laid up toward the centre of the car in between studs.

Lay each cable across toward the centre as shown below, then secure them down by reconnecting the right angled light grey pieces over the top.

Reconnect some of the pieces we removed earlier, then connect the two tail lights to the Micro Battery Pack ports. Turn ON the battery pack to test the tail lights are working OK.

Disconnect the trans orange angled tiles, then take a White 15cm Bit Light and with the cable facing the right, place it over the front of one of the blue angled plates. Secure the Bit Light in place by reconnecting the trans orange angled tile over the top, then reconnect it to the left side of the rear of the car.

Repeat this step to install another White 15cm Bit Light to the right upper tail light section except this time, ensure the Bit Light cable is facing the left side.

8.) Connect the two upper tail lights to the Micro Battery Pack, then turn the Battery Pack ON to test all the tail lights are working OK.

9.) Disconnect the steering wheel and lay the two cables from the head lights in between studs before reconnecting the steering wheel over the top.

Eliminate excess cables by grouping them all together and twisting/folding them around each other into a neat bunch

Place the battery pack at the back of the car and tuck the bunched up cables underneath. Ensure the battery switch is facing up for easy access. Place Ron in the car to secure the battery pack in place, then reconnect the windows and roof.

Turn ON the battery pack again then, place the flying car back into the tree.

10.) We will now begin lighting the castle. First disconnect the left section by pulling them out at the technic pins, then disconnect the following sections from Professor Severus’ office.

11.) Take the candle and disconnect the flame piece. Take a White 15cm Micro Bit Light and carefully bend the LED down as shown below. Place the micro light inside the top of the candle (with led facing up), then secure it down by reconnecting the flame piece.

Fold the Bit Light cable down the side of the candle before reconnecting the candle to the professor’s office. Ensure the cable is facing behind and tucked behind the chair and shelf toward the right.

Thread the other end of the Micro Bit Light through the hole on the top right (next to the technic pin), then pull it out from the other side and connect it to a Micro 4-Port Expansion Board.

Note – We will connect the micro bit light up to a flicker effects board later on. Leave this component as is for now. 12.) Disconnect the lamp from the desk as well as the rigid brick underneath, then disassemble the lamp as shown below:

Using a pair of scissors, carefully snip off the tip off the dark grey wheel piece. Take a White 15cm Bit Light and place it directly over the grey stud (under the tip we snipped off). Secure the Bit Light in place by reconnecting the dish with trans clear round plate over the top.

Thread the other end of the Bit Light down the hole in the centre of the desk. Pull the cable all the way out from underneath, then reconnect the lamp on top of the desk and the rigid brick underneath. Ensure the lamp cable is facing the back.

13.) Connect the Bit Light to a 6-Port Expansion Board, then reconnect the desk to the office floor.

Remove the black chair and lay the cable from the lamp down in between studs towards the back wall before reconnecting the chair over the top. Reconnect the Severus to his chair.

Disconnect the following pieces so that we can remove the two grey bricks with clips, then bring the expansion board up from underneath.

14.) Take the two wall lamps and disassemble them as per below:

Take a White 15cm Bit Light and thread the connector end through the bottom (larger hole) of the trans yellow cone piece. Thread the light all the way through until the LED is right up inside. Secure the Bit Light in place by reconnecting the round plate underneath and round plate with tip on top. Ensure the cable is facing the back of wherever the LED front is facing.

Reconnect the lamp to one of the grey bricks with clips, then bring the cable underneath the base of the grey brick. Thread the Bit Light cable down the space on the top left of the professor’s office. Pull the cable all the way up from the other side (middle area). Ensuring the cable underneath the grey brick is laid in between studs, reconnect this section to the wall, then connect the bit light cable to the 6-port expansion board.

15.) Repeat the previous step to install another White 15cm Bit Light to the wall lamp on the other side.

Take the AA Battery Pack and insert 3x NEW AA Batteries. Connect the Battery Pack cable to the 6-port Expansion Board, then turn the battery pack ON to test the desk lamp and wall lights 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 or expansion board). To correct any issues with expansion board ports, please view the section addressing expansion board issues on our online troubleshooting guide. 16.) Take a 15cm Connecting Cable and connect it to the 6-port expansion board, then thread the other end of the cable down the middle space, to the inside of the room. Thread it back outside via the same hole we threaded the micro bit light through (top right) and pull it out through the other side.

Bring this section of the castle close to the main section, then thread the cable through the hole that leads into the main section of the castle via the left hole in the grey technic brick. Pull the cable out through the other side, then reconnect both sections together ensuring the micro 4-port expansion board is still accessible.

17.) Neaten up the cables above Professor Severus’ office by folding and twisting them around each other into a neat bunch, then stick the expansion board to the inside of the roof area using 2x Adhesive Squares.

Bring the battery pack cable over to the left side ensuring it is laid in between studs, then reconnect pieces we removed earlier. Check to make sure there are no dangling cables visible by pushing any excess cables up into the roof area.

Hide the cables on the right side behind the shelf.

18.) Take a 50cm Connecting Cable and connect it to the Micro 4-Port Expansion Board (bottom port). Hide the expansion board in between the grey wall and pillar, then disconnect the two tiles along the ground on the right. Lay the 50cm Connecting Cable across in between studs before reconnecting the tiles over it.

Disconnect this middle section from the tower section by pulling it out at the technic pins, then thread the 50cm cable through hole on the bottom right side. Pull the cable all the way out from the other side.

19.) Disconnect the following sections above, then pull the 15cm connecting cable up from underneath. Bring the cable over the left side of the wall and lay it in between studs before reconnecting one of the sections we removed earlier over .

Neaten the cables going down the side of the tower by first grouping the three cables together at the bottom of the tower. Slightly disconnect the dark tan plate on the right corner, then tuck the three cables underneath and pull the cables up from the other side to eliminate excess cables from the outside of the tower. Reconnect the plate at the corner as shown below:

23.) Bring all the cables and expansion board inside the front entrance roof section. Ensure the cables are brought through the right side of the dark grey plate. Neaten up the cables by twisting/folding them around each other a few times to form a neat bunch. Tuck the bunch of cables along with the expansion board inside the roof section before folding down the right side of the roof to secure everything in place.

Secure the cables running down the side of the tower using sticky tape.

24.) Take 2x Adhesive Squares and stick them to the back of the 6-Port Expansion Board at the bottom of the tower. Mount the expansion board to the base of the ground floor underneath the stair case, then secure the cables underneath the dark grey tile as shown below:

25.) We will now light up the fireplace and candles inside the great hall. First disconnect the following table, then follow the images below to disconnect sections to remove the entire fire place.

Remove the following black brick from the fireplace, then take a White 30cm Bit Light and with the cable facing the back, place it over the right stud, where the flame was connected to. Disconnect the flame piece from the black round plate, then use this round plate to secure the Bit Light down.

26.) Repeat the previous step to install another White 30cm Bit Light to the stud on the left, then while ensuring both cables are laid in between the brown studs behind, reconnect the black piece we removed earlier, along with the surrounding fireplace hood section.

Take the two flame pieces and carefully snip off the tip ends of each piece using a pair of scissors. This will allow us to then reconnect them to the black round plates with bit lights underneath.

27.) Take the two cables from behind the fireplace and thread them up the following gap in the ceiling. Pull the two cables all the way out from the top, then reconnect the fireplace.

Secure the two cables in between studs underneath the following angled roof brick, then pull the cables back inside as shown below:

28.) Reconnect the left roof section above the entrance, then bring the 15cm connecting cable from this side across to the right and connect it to the IN port on the Flicker Effects Board.

Take the two Bit Light cables from the fireplace and connect each cable to the OUT ports on the Flicker Effects Board. Turn ON the AA Battery Pack to test the fireplace lights are working OK with the flicker effect.

29.) We will now light up the candles on the roof. First disconnect this section by pulling them out at the technic brick holes, then disconnect the candle and flame pieces as shown below:

Take out a White Micro 15cm Bit Light and carefully bend the LED back as shown in the below image.

Thread the Bit Light into the hole of the candle piece as shown below, then reconnect the flame piece. We want the LED to be as close to the flame tip as possible therefore, threading the cable all the way to the end of the hole is not necessary.

30.) Reconnect the candle to the roof frame, then repeat previous process to install another 3x White Micro 15cm Bit Lights to the remaining 3x candles.

31.) Reconnect the candle frame section to the Great Hall roof, then thread each candle light cable through the following holes of the black technic brick above.

32.) Connect each Micro Bit Light to the ports on the Micro 4-Port Expansion Board. Ensure you follow the below images to ensure you are connecting the light cables into each port correctly.

Take a 5cm Connecting Cable and connect it to one of the larger ports on the Micro 4-Port Expansion Board. Connect the other end of the connecting cable to the remaining OUT port on the flicker effects board. Turn the AA Battery Pack ON to test the candle lights are working OK with the flickering effect.

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. 33.) Turn the set over to the front, then take 4x Adhesive Squares and stick two to the back of the Flicker Effects Board, and another two to the back of the Micro 4-Port Expansion Board. Mount the two boards to the right side of the black technic brick as shown below:

Neaten up the wiring by grouping the two bit light cables from the fireplace and twisting/folding them around each other into a neat bunch. Tuck the bunched up cables through the archway space on the right, then pull the micro bit light cables toward the right side as shown below. Do your best prevent any wiring from dangling down and being seen from the inside of the hall.

The last step is to reconnect the main roof section.

This finally completes installation of the Light My Bricks Hogwarts Great Hall Light Kit. We thank you for purchasing this product and hope you enjoy!

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.) We will first light up the train station. First remove the train, then disconnect the bridge section and the following lamp sections by unclipping them from the wall.

2.) Disassemble the lamps as shown below, then take a White 30cm Bit Light and thread the connector end of the cable through the base (larger hole) of the trans yellow round brick. Thread it all the way in, then secure it in place by reconnecting the black clip on top. Ensure the LED on the bit light is facing the front of the brick.

Repeat this process to install another White 30cm Bit Light to the other lamp.

3.) Carefully disconnect the upper part of the wall so that it creates a gap where the lamps were connected to. Thread each lamp cable all the way through this space, then reconnect the lamp to the clip. Ensure the cables are laid neatly in between the studs as shown below:

Once the lamps are reconnected, carefully reconnect the upper wall section to close up the gap while ensuring the cables are laid neatly in between studs.

4.) Turn the station around to the back and fold down the cables against the wall so they run flat down the wall.

Secure the cables underneath the following bricks. First disconnect each brick, bring the cable inside, then reconnect the brick while ensuring the cable is laid in between studs. This will also eliminate unwanted cable from behind the set.

5.) Take a 6-Port Expansion Board and connect the two bit light cables to it. Take your AA Battery Pack and insert 3x AA Batteries to it. Connect the battery pack to the expansion board and turn it ON to test the lights we have installed so far are working OK. USB Power Cable has replaced Flat & Round Battery Packs (CR2032) as of June 2022 due to child safety regulations. Please use the USB Power Cable in place of the Battery Pack.

Take a White 15cm Bit Light and with the cable facing the clip, lay it over the stud. Secure it in place by reconnecting the lamp piece over the top. Thread the cable through the top of the black plate’s clip, then pull it all the way out from underneath as shown below:

7.) Carefully disconnect the upper section of the wall to create another gap, then thread the bit light cable through the gap in between studs. Reconnect the lamp back to the wall, then close up the gap ensuring the cable is neatly laid in between studs.

Turn the set around to the back again and fold the cable down along the back of the wall. Turn the set onto it’s front so we can access underneath, then disconnect the long black brick. Connect the bit light cable to the next spare port on the 6-port Expansion Board below, then turn ON the battery pack to test the light is 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 or expansion board). To correct any issues with expansion board ports, please view the section addressing expansion board issues on our online troubleshooting guide. 8.) Take a 30cm Connecting Cable and connect it to a spare port on the expansion board, then reconnect the long black brick ensuring you first pull the 30cm cable all the way out, and pull the White 15cm Bit Light cable all the way inside. Also make sure each cable is laid in between studs before completely closing up the gaps.

9.) From the back of the set, take the other end of the 30cm Connecting Cable and thread it through the first gap on the bottom of the steps, then pull the cable all the way out from the front. From the front of the set, thread the cable back through the next gap up the steps and pull it all the way out from the back of the set.

10.) Partially disconnect the top section above the steps to create a gap, then bring the cable all the way up and thread it in between studs through this gap we created. Pull the cable all the way out from the other side, then close up the gap ensuring the cable is laid in between the studs.

Thread the cable underneath to bring the cable around to the front side

11.) Take the bridge section we removed earlier and turn it onto it’s back so we can access underneath. Take a White 15cm Bit Light and a provided LEGO Trans Clear Plate 2×2 with rounded bottom. Use this LEGO piece to install the Bit Light underneath the front platform of the bridge by connecting it to the roof with Bit Light LED facing down the centre of the trans clear piece. Ensure the other end of the cable is facing the bridge.

From the back of the bridge, partially disconnect the top section to create a gap above the dark grey brick. Bring the cable through this gap, then reconnect this section to close up the gap ensuring the cable is laid in between studs.

Follow the below images to continue to thread the cable around sections to eliminate excess cable:

12.) Take a White Strip Light and using it’s adhesive backing, stick it to the base of a provided LEGO Plate 1×6. Take the other end of the White 15cm Bit Light from underneath the bridge and connect it to the Strip Light.

Take the other end of the 30cm Connecting Cable from the other side of the station and connect it to the other side of the Strip Light. Mount the strip light underneath the bridge in the following position, then reconnect the bridge to the train station. Eliminate excess cabling from the White 15cm Bit Light by looping the cable underneath the strip light’s lego plate.

Eliminate excess cabling from the 30cm Connecting cable by twisting the cable around itself a few times, then tucking it in to the space underneath the steps as shown below ensuring they are tucked in between studs.

Follow the below images to continue to hide excess cables underneath and in between pieces.

Finally, turn ON the battery pack to test all lights installed to the train station are working OK.

13.) We will now light up the Hogwarts express train. First, disconnect the middle and back carriages, then disconnect the following sections from the front of the train.

14.) Take the following top section and disassemble it. Take a White 15cm Bit Light and with the cable facing the clip, place it over the gold stud. Secure it in place by connecting a provided Trans Clear Round Plate 1×1 over the top.

Thread the other side of the cable through the gap behind, then pull it all the way out from underneath. Reconnect the gold clip to the black piece, then reconnect this section to the front of the train.

Ensure the cable is laid in between the light grey studs before reconnecting the round Hogwarts Express dish piece over the top.

15.) Take the bottom section and disassemble it as per below.

Take a White 15cm Bit Light and place it over the left stud as per below. Secure it in place by connecting a provided LEGO Trans Clear Round Plate 1×1 over the top. Repeat this process to install another White 15cm Bit Light to the other side, securing it in place with another provided LEGO Trans Clear Round Plate 1×1.

Ensuring both cables are laid in between studs, reconnect the sections we removed earlier, then reconnect this bottom section back to the train.

16.) Turn the train over onto it’s side and disconnect the two sections underneath.

Take the three Bit Light Cables and thread them through the following gap in the middle of the back section we removed earlier, then connect them to a new 6-Port Expansion Board.

17.) Reconnect the two sections back underneath the train, ensuring all cables are laid in between studs.

Take a Round Battery Pack and insert 2x CR2032 Batteries to it. Connect the battery pack to the 6-port expansion board and turn it ON to test the lights on the front of the train are working OK.

Using the LEGO removal tool, disconnect the following black piece from the back of the train, then pull one of the 15cm cables all the way out towards the back. Secure the cable by reconnecting the black piece over the top ensuring the cable is laid in between studs.

Twist and fold excess cabling from underneath the train, then tuck them in neatly to prevent them from dangling down. Bring the other 15cm connecting cable toward the back and pull it up the left side of the train as shown below:

19.) Turn the train over and disconnect the following sections from the back.

Bring the other end of the 15cm cable from the left side and lay it in between studs before reconnecting the red 1×3 plate.

Lay the cable in between studs towards the front of the train, then secure it underneath the black and red plates.

20.) Connect the 15cm connecting cable to the IN port on the Flicker Effects Board.

Take the steam control cab and disconnect the following section from the back. Disassemble this section as per below:

21.) Take 2x White 15cm Bit Lights and hold them together over the studs on the front of the black brick. Ensuring the cables are facing the top of the black brick, secure them in place by reconnecting the red plate over the top.

Bring both cables over the top of the black brick, then reconnect the light grey brick over the top, ensuring cables are laid in between studs. Reconnect this section back to the steam control cab

22.) Take the following flame pieces and using a pair of scissors, carefully snip off the tips from the bottom. This will allow us to then reconnect them back to the control cab with Bit Lights installed underneath.

Connect the two bit light cables to the OUT ports on the Flicker Effects Board, then reconnect the control cab back to the train.

Eliminate excess cables by twisting/folding the bit light cables around each other so they come together in a neat bunch, then tuck them (along with the effects board) inside.

23.) Connect the other end of the 15cm Cable from the back of the train to a new 6-Port Expansion Board. Connect your Round Battery Pack to a spare port on the expansion board and turn it ON to test the flickering lights (along with the front lights) are working OK. USB Power Cable has replaced Flat & Round Battery Packs (CR2032) as of June 2022 due to child safety regulations. Please use the USB Power Cable in place of the Battery Pack.

25.) Take the middle carriage and disconnect the roof and front wall. Reconnect the carriage to the front carriage, then bring the 15cm connecting cable inside.
