I just upgraded my new GTi300 with Euro turn signal en H4 led. my local Dealer were i purchased my GTi300 did the turnsignal mod and put on the new h4 led, Im very satisfied with thr result, at the moment the H4 led was out of stock on the dealer so I ordered from ebay en bring the led to them, they remove the usa turn signals and activate the original ones, its a cleaner look now, just want to share, and maybe new people gti300 owner wants the turn signal mod can ask their dealer to do it ! i was charged very cheap for that. it was worth every penny !!!!
