Our PT cruiser has an LED KIT installed on the bottom of our car that has a special ability to change colors at the push of a button .The LEDS are in tubes much like the polycarbonate blades and are very bright.Now a thought occrured to me, like applying this same idea to the FX sabers.Just think of having one saber that can change from bright blue, to bright green,bright purple and bright red ,or many other colors.
Now I can't do anything with mine because i'm not smart enough,but if anybodyelse knows that would be pretty cool. ;D
