I have a bi xenon kit fitted at the moment, and want to upgrade to having xenons in both parts of h/lights, ie, main and dipped, instead of the bi xenons I'm using in just the dipped part. The headlights themselves are mk5 XR3i/RS2000 lights, how easy is it to add another kit? Is it just a case of fitting another kit and wiring it up or is there likely to be any problems?
