I can't specifically answer your question on V4s and the OEM Xenon's but I know we can get into the headlight assembly relatively easily. I was planning on getting LED bulbs for my angel eyes to get rid of the gold-ish tint to them as well. I don't see why the V4's would be much different to installing a different LED brand.

And* installing the V4's without the lights already attached to the car makes their install that much easier. You eliminate the worst step, getting into the light assembly to make the change.
