Are the V4's not gonna fit or why are you all going for the V2's?
From lots of reading on other forums, looks like the V4 is the way to go....it has a built in night controller, more LED's per ring (less spacing of the led's -the rings look more compact compared to V2) and a lot brighter.
What kind of shop would undertake this kind of job?id look for one in my area since I don't feel like baking my headlights to open them up..
