New VWs use LED headlights in which the bulbs cannot be replaced, since they're meant to last forever. And even halogen bulbs are known to last longer than xenons. HIDs generally have great width, but they lack high beam range. I think HIDs only have two advantages over halogens: width and colder color. Currently car manufacturers aren't hesitating in replacing HIDs with LEDs, and that tells a lot. According to multiple long term tests conducted by a Finnish car magazine TM, xenons lose more of their range than halogens do.
