I order several sets from Amazon but liked the battery operate LED type best. The selection always changes but I found a small set with 40 lights and that was just about perfect. I used and x-acto knife to create small holes in the back and inserted the tiny lights inside. Easy and very effective.
And,as part of the introduction, I asked others to send along photos of their Ledge Village. I have a webpage where I share display ideas for Ledge Village here. I got some photos of some wonderful displays.
