Before we start - check you have everything you need.
These sets come with the following parts:
- 8 x White 15cm Flashing Bit Lights
- 1 x White Strip Light
- 1 x 12-Port Expansion Board
- 2 x 15cm Connecting Cables
- 1 x Micro Battery Pack with LR44 Batteries
- 8 x Trans-Red 1x1 LEGO® studs
And of course you'll need LEGO® set 21306 - The Yellow Submarine!
Lighting the Portholes
First we take apart that cabin roof piece - it's easy to get the porthole bricks out.
We can't use the flat round 1x1 Trans Red Tiles provided so have to swap these for 1x1 round plates instead. They have a bit more space inside for this kind of use.
Lighting the Underneath
This one should be nice and easy - to get an ambient glow you just need to mount a strip light underneath and hide the cables.
Dismantling the end to fit the cable should be quite straightforward. Remove the upper section to reveal that odd hollow compartment, remove the red arch too, and there's two 2x2 L-shaped plates. Those come off and then you can get to the 2x6 curved piece and that nice quarter-round piece underneath. It's easier done than described!
Once done you can see a clear path to get the cable to the inside chamber.
You'll need to carefully hold the cables clear of the studs when re-attaching the hull pieces:
Bringing it all together
Then re-fit the red and white pieces to trap the cables neatly and and braid all those bit light wires together into two bundles as shown below.
Finally the top goes on and the battery pack is positioned with the on/off switch facing upwards for easy access.
And here we are - this is what you should have at the end!
