Recently, I got the S-12012 Light Stax kit with 50 (!) light bricks. They are different from those described in this question, but they are much cheaper, colorful and with blinking/pulsating effects. However, there is one disadvantage: all bricks have to be attached to each other to lighten up. So if I wanted to light up different areas of my set I would need several of the 4x4 battery bricks (there is only one in each kit).

My question: Is it possible to to connect/solder wires between the bricks to extend the range?

The lights are LEDs, and it does not matter how the bricks are connected as long as one stud is connected to the underside of the next brick. There are contacts on all studs and undersides. I want to avoid damaging the bricks with my limited soldering skills.

I tried to use the 8886 PF Extension Wire, but that did not work. The contacts don't match.

Pictures 3 and 4, respectively, are close up photos of the studs and undersides of the bricks. Does this help to tell how extension wires could be attached?

  • Is there a single LED in a 2x2 and 2x4 brick? How do you change the effects? – Uli Apr 16 at 23:04
  • lightstax.eu sells single extension cables ranging from 10-80cm for little money. You could cut the leads and adjust their length, rather than modifying some LEGO plates to act as sockets. Just an idea... – Uli Apr 17 at 0:00
  • @Uli Ha, I wasn't aware of the cables, thank you for the hint. This doesn't answer my question but it definitely solves the issue very nicely. The effects are triggered by pressing or holding the button on the battery brick. It is also supposed to react to sound but I haven't figured out how. – Aziraphale Apr 17 at 5:48
  • @Uli Yes, there is one LED in each brick. Most of the bricks in this set are semi transparent, a few are clear transparent. – Aziraphale Apr 17 at 5:54
  • However, with each brick being THRU as well, these off-the-shelf extensions are even YY cables. Still, is it possible to tinker one? Both pins sit on a single stud. That's tricky! – Uli Apr 17 at 7:31
