Ok, quick Q... I've looked through previous threads but still confused...

Non AFL Xenon lights, if your car doesnt have them, how easy are they to fit? Do you need any extra bits that arent in the headlamp?

I know you can do something with HID kits, but was wondering if it was just a simple case of changing the headlamps? Anyone actually fitted Xenon lights? (Not HID kits)

Anyone? Cheers...
