Hey is there any aftermarket company that makes projector headlights that can handle 4300K real conversion kit xenon?

Any kit can handle the lights. I am pretty sure they actually burn cooler than normal bulbs. There are plenty of companies that make HID conversion kits for any bulb. I have the 6000k HID conversion kit in my 850. I paid $350 shipped and they are awesome. Only thing you need to worry about is finding the projection kit

Projectors will have to be custom made. Check over on Volvospeed for the ones people have made over their for themselves.
