Quoted from The_Dude_Abides:TRON LE has lit color changing ramps, chrome rails and lock down bar & legs, drop targets instead of stand up targets, moving recognizer, and an extra multiball (daft punk multiball). The playfield on the LE also came with an extra coat of clear.
Also silver-lined inserts, the spinning disc changes from Red to Blue, the Tron inserts are different & the Recognizer has individual inserts that roam & correspond to each target.
