They are so cool Yeah it is just plug and play although I thought the locators on the back would sit in the bowls but then I suppose they are generic and so held in place by the chrome rings (although I did mine black) I haven't done the wiring in the car as no column yet or dash so I will wire up the halos when I get chance separately for a quick lookAre they not COOL or what !!!!
Straight swap out ????
Doesn't the kit just plug in to the existing 3 pin Female connection ??
Then a night shot should be good
