BTW, HID upgrades are rarely done these days, firstly because HID is now old tech (superceded by LED), and also because of the massive cost of a road-legal retrofit that must include headlamp washers and automatic height adjustment.
I other words, an illegal upgrade to HID (i.e. without also retrofitting the other mandatory and expensive items) is a waste of time because at this point you might as well just fit LEDs which will be equally illegal but much brighter.... to clarify, I am not condoning either, I am just trying to explain why HID conversions (both legal and illegal) fell out of favour in recent years.
