Very Cool. Have got a DE Star Wars as well and been throwing up wether to do the LED thing. It's a reallly fun game to play and the wife and kids love it and been told this pinny is a keeper.
On our pin I have an LED strip in red behind the plastics at the top of the playfield, which helps light up a dark area up there. The blue LED's in R2D2 really looks great. Wasn't sure how to light up the Death Star and I like what you have done with the red. Will get some of these and play around as well.
Nice work.
