the best way is to retrofit some audi or s2000 projectors in place of the aftermarket low beam projector. The audi a4/s4 would probably work best because it has great mounting points and is one of the smallest hid projectors out there. The s2000 would be my ideal choice because it is a better projector but they are much harder to retrofit because there are no mounting points. Also, the Audi projectors (valeo makes them) are the cheaper projectors out there, bosche, hella or kioto makes higher quality projectors than valeo. You find those on bmw's, mercedes, and exotic cars.
