There is definitely a shortage of lightup LEGO minifigs in the world. Fortunately for us, Gizmodo has posted a gallery showing the bits used to mod a Clone Trooper minifig with a light up helmet. If we can manage to squeeze some LED’s into LEGO lightsabers we’ll be in business! Would go well with the lightup lightsabers from the Episode:III sets! (thanks Richard!)
