Inspired by the electronic Obi Wan and a few posts in the review thread, I tried my hand at a light up Anakin saber. I'm pretty happy with it. It is a tad wider than his plastic saber, but it doesn't look too bad. I made it from a small led light from target. It is silver metal and has a blue LED. I had to switch the bulbs, as the silver case had a white light, and the blue light had a blue case, which was actually goldish metal with blue paint. (I'll use it for a different saber.)
It cut off the trim from 12" Anakin's saber to glue onto the metal one.
The light was on clearance at Target for 2 bucks. They had others at regular price as well. A double Maul saber would rock! I can't wait to try.
