I have two Alice in Wonderland PODM displays that I put together myself (if I can do it, anyone can with a little patience and planning!) based on a tutorial someone posted on this forum a long, long time ago. I did research first, and the consensus seemed to be LED lights, so that's what I used. I found small strings of them at a craft/hobby store we have here in the US (Hobby Lobby ... I prefer Michael's but they didn't have what I needed). They were inexpensive, they are battery-powered, and they can be turned on/off easily with a switch, so I can light my PODMs periodically to show them off or admire them but don't have to worry about leaving the lights "burning" for too long (which most people also caution against). If I can find the original thread, I'll add a link here ... but you might search the forum for "PODM" and "display." It took some work to get them just right, but they look AWESOME. Good luck in your quest!
