Really enhances the set for display!
I'm very pleased with the lights that I ordered. They were a bit fiddly to install and the instructions were a bit vague (just photos, no text) but I actually quite enjoyed that and imagine whoever is building these lego sets would too.
The lights look great on my bookcase and I've used a battery eliminator so that I can keep them plugged in at the wall.
Brilliant product, great price, 10/10 would recommend!
