I’m in love

This light set is so gorgeous that I bought the Lego just so I could do the lights. The quality of everything is great and instillation was pretty easy. I did have some trouble with pinching wires too tight but the outcome is well worth the stress of troubleshooting.

Beautiful lights set

Really makes this set come to life.

Smaller scale kits are difficult to deal with as lots of fiddly bits sometimes are just hanging on waiting for a movement or bump to set them free, but despite that on the Lego side of thing the Light My Bricks kit was a pleasure to build and complete.

Great election of parts

Purchased for use in other projects, but this set would definitely make the Trafalgar Square set shine!
