Topic: Lifelites
I'm sure some people already know of this site, but for those of you who don't, I found an amazing site called Lifelites.com. They have an enormous selection of all different kinds of LED lights specifically made for LEGO® and other brick toys! I've come up with tons of ideas in my head on what you could use these for and I'm sure there are hundreds more I haven't even thought of. One of their coolest items is this. The wire is invisible.
