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!
Lighting the Car
1.) Start by disconnecting the following sections of the front and bottom of the car (trans clear tiles, 1×12 plates, and front bumper section).
2.) Take a White 15cm Bit Light and with the cable facing down, place it directly over one of the front grey studs. Take a provided Trans Clear Round Plate 1×1 and connect it over the top to secure the Bit Light in place.
Install another White 15cm Bit Light to the other headlight using the same method as above.
3.) Lay both Bit Light cables down the side of the White 2×4 plate and then reconnect the front bumper section over the top.
Bring both cables down the base of the car and then thread each cable through the spacing in between the back wheel and side of car.
Pull each cable up from the inside of the car.
4.) Reconnect the two 1×12 plates ensuring you secure each cable in between studs of each plate.
5.) We will now install the tail lights. First disconnect the whole section as well as the 2 curved pieces as per below:
Continue to disconnect pieces from the back of the car.
6.) Disconnect and disassemble the four tail light sections as per below:
7.) Take another White 15cm Bit Light and then thread the connector side through the top of one of the Light Grey Round Plates. Thread it all the way through and then slightly bend the Bit Light so that it sits flat against the top of the plate.
Take one of the provided Trans Red Round Plates 1×1 and then connect it over the top to secure the Bit Light in place. Reconnect this plate to the back section ensuring the cable is facing toward the middle of the car.
8.) Repeat previous step to install another 3x White 15cm Bit Lights to the back of the car.
9.) Reconnect the back section to the car and then take the two Bit Light cables from each side and lay them in between studs before reconnecting each curved white piece on top.
Continue to reconnect surrounding pieces to the back of the car.
10.) Take an 8-port Expansion Board and then connect the four Bit Light cables from the back of the car to the inside ports.
Wind the four cables around the expansion board 3–4 times until the board is close enough to the top of the car seat then connect the two Bit Light cables from the front of the car to the out side ports.
11.) Take the 50cm Connecting Cable and then thread one side underneath the car and then up the spacing in between the back wheel and side of the car. Pull it up from the top of the car and then connect it to one of the spare ports on the expansion board.
Neatly place the expansion board on top of the back seat then add the guitar and minifigure.
Test the lights we have installed so far by connecting the other end of the 50cm connecting cable to a spare expansion board and then connect the USB Power Cable to a USB Power Power Bank, USB to AA Battery Pack, or USB Wall Adaptor (each sold separately) and turn it ON to test the front lights are working OK.
This completes the installation of lights for the car and we are now ready to move on to lighting the Downtown Diner.
Lighting the Downtown Diner
1.) First remove the top two levels of the Downtown Diner then disconnect the lamp post and 2×4 plate underneath.
Disconnect the following two grey tiles above where the lamp post was connected to.
2.) Take the LEGO Lamp Post with Bit Light installed and then connect it to the base plate ensuring the cable is facing toward the building. Gently bend the corner of the base plate down so that the bottom right corner of building disconnects and provides a gap underneath. Thread the lamp post cable in between this spacing and then pull the cable up from the inside.
Pull the cable all the way up eliminating excess cable between the lamp post and building and then reconnect the bottom right corner of the building to the base plate. Ensuring the lamp post cable is laid in between studs, reconnect the tiles we removed earlier
3.) We will now install flashing lights to the jukebox. First disconnect the jukebox and then disassemble pieces as per below:
4.) Take a Flashing White 30cm Bit Light and then place it (with cable facing toward the back) directly over the top of the stud toward the front of the jukebox. Reconnect one the angled trans clear tiles over the top securing the Bit Light in place.
Repeat this step to install another Flashing White 30cm Bit Light to the right side then reconnect surrounding pieces of the jukebox.
5.) Reconnect the jukebox to the inside of the diner and then remove the following sections which make up the bench in the corner, side tables and extra seats.
Lay the two cables from the jukebox down and around the bottom corners of the diner. Secure them in place by first reconnecting the bottom of the corner seat, followed by the table, then the remaining chairs.
6.) Take the 8-Port Expansion Board and then connect the two cables from the jukebox as well as the lamp post cable to the inside ports.
Pull the three cables up the corner of the diner and then use tape to secure them down.
Using 2x Adhesive Squares, mount the expansion board to the inside of the diner in the following position.
3.) To prevent cables from dangling down you can secure them underneath the top tiles by laying them in between studs.
4.) Take the USB Power Cable and then place it behind the Downtown Diner as per below. Bring the cable over the wall and then connect it to a spare port on the 8-port Expansion Board.
Secure the USB Power cable by laying it underneath the tile on the top.
5.) Take the other end of the 50cm Connecting Cable from the Car and then connect it to a spare port on the expansion board. Secure the cable in place by laying it underneath one of the tiles on the top of by building.
Turn ON the power and ensure the lights we have installed so far are working OK.
6.) We will now slightly modify the ‘Diner’ sign on top of the first floor so that it sits slightly back from original position. We need to create this little gap in order for us to install strip lights to shine on the sign. To start, first disconnect both sections of the sign.
Separate the letters ‘n’, ‘e’, and ‘r’ and then disconnect the light grey 1×1 plate from the section in between ‘e’ and ‘r’. Hold onto this 1×1 plate as we will bring this over and use this to connect to the section in between ‘D’ and ‘I’.
Disconnect the 2 sections in between letters ‘D’ and ‘I’ and then remove and discard the light grey 1×2 plate from the bottom of letter ‘D’. Take the light grey 1×1 plate we disconnected earlier and then connect it to the pink stud at the lower front of the ‘D’.
There were two sections that were in between ‘D’ and ‘I’. Discard the front section and then replace it with just the back section to connect ‘D’ and ‘I’ together.
Take the ‘R’ and then reconnect the section in between ‘R’ and ‘E’ to the bottom left of ‘R’(section we removed the 1×1 plate from).
Take the ‘E’ and then disconnect and discard the section connected to the bottom right then reconnect ‘E’ to the new section next to the ‘R’
Take the ’n’ and then remove the light grey 1×1 plate from the bottom right. Reconnect the ’n’ to the ‘E’.
Place the two sections of the ‘Diner’ sign together and it should now look like below:
You should also have the same excluded pieces shown underneath. Set this ‘Diner’ sign aside for now and proceed to the next step.
7.) Take 5x White Strip Lights and 5x 5cm Connecting Cables and connect all the strip lights together leaving one side of a 5cm connecting cable disconnected.
8.) First disconnect the following tile on the front right section of the Diner and then lift up the top section to create a gap underneath as per below:
9.) Insert the end of the 5cm connecting cable through this space and then pull the cable up from the inside of the Diner. Connect this cable to the 8-port expansion board inside.
10.) Pull the first Strip Light all the way out from the front of the Diner and then using it’s adhesive backing, stick it underneath the top section on the eave right above the front door.
Reconnect the top section and tile we removed in step 8.
11.) Using the adhesive backings, stick the next two strip lights in the following positions along the eaves of the roof .
12.) We will now need to thread the remaining two strip lights up the left corner of the roof. First disconnect the top white section followed by the round corner section as per below:
13.) Thread the two strip lights up through the space in the corner and then pull them all the way up from above.
Carefully reconnect the round corner section ensuring the cable is laid on the right side as per below:
Reconnect the top white section.
14.) Turn the building around and then using the adhesive backings, stick the two strip lights to the following positions. These will be used to shine on the newly positioned ‘Diner’ sign.
15.) Reconnect the two sections of the Diner sign and then turn the power ON to test and confirm the lights we have installed so far are working OK.
16.) We will now install a light to the lamp post on the left corner of the second floor. First disconnect the rails on each side, followed by the lamp post.
Disconnect the trans clear minifigure head as well as the dish above.
17.) Take a White 30cm Bit Light and then thread the connector side through the bottom of the dish piece.
Place the other end of the Bit Light inside the bottom of the trans clear minifigure head and then from the top of the dish, pull the cable all the way up and then reconnect the two together. This should secure the bit light in place and look similar to below:
18.) Reconnect the dish to the lamp post and then reconnect the lamp post and rails back to the second floor.
We will leave this section for now as we will connect the lamp post cable to the top floor later.
19.) Take the entire second floor and the place it on it’s side as per below:
Take 2x White Strip Lights and then stick them to 2x provided LEGO Plates 1×6.
