xenon and HID are two different things to what they are referring .
since when are oem xenon lamps referred to as HID?
at no point does it refer to xenon lamps/retro fits, it's purely aimed at people who have changed their halogen bulbs for HID's.
beam patterns are then incorrect, and hense why VOSA are acting on it.
Either way, a close mate whos a Mot tester has told me the same thing, so for me personally, won't effect my situ.
