I agree the legalities are a big grey area and it can be difficult to understand sometimes, on most conventional halogen headlamps they consist of a bulb, bulb shield, reflector and a headlamp glass. The bulb lights up, the bulb shield directs the light onto the reflector, the reflector then directs the light onto the headlamp glass which creates a beam pattern directing it onto the road. on these types of headlights HID kits are totally illegal because the headlamp glass cannot sufficiently direct the beam pattern, in the same way if you take a car with this type of headlamp abroad you need to fit beam directors to your headlights so you do not dazzle oncoming drivers. for example i fitted HID's to my sister in laws Audi A2 and they were illegal.
The GTV however has projector headlamps so therefore the light is projected onto the road surface not directed onto the road surface. the beam pattern of the headlamp is not determind by the headlamp glass or reflector but by the projector units, in the same way in order to drive a GTV abroad you only need to flick the switch at the back of the headlamp.
If the car is put through an MOT test the tester is checking primarily for beam pattern and that the aim is correct, if you were to present a car with reflector headlamps for an MOT test with HID's fitted it would most certainly fail however a GTV with HID's fitted will pass an MOT test as mine has done twice now at different MOT stations and any roadside checks so therefore complies with law.
However..................a HID kit fitted to a GTV could be rendered illegal if the MOT tester checks the type approval documents for the GTV.
