Ok bit of an update here, i have Googled this and read up on many sites and it looks as though Figo is correct, it is all down to the head light unit being "E" marked. this statement is from the dept of transport.
"In the Department’s view it is not legal to sell or use after market HID lighting kits, for converting conventional Halogen headlamps to HID Xenon. If a customer wants to convert his vehicle to Xenon HID he must purchase completely new Xenon HID headlamps. The reason for this is that the existing lens and reflector are designed around a Halogen filament bulb, working to very precise tolerances. If one places a HID “burner” (bulb) in the headlamp, the beam pattern will not be correct, there will be glare in some places and not enough light in other places within the beam pattern".
Department for Transport (2006)..
As for the MOT as long as the beam is within alignment then the car will pass, the problem is, that the MOT does NOT test for glare, it is only tested for alignment, and if the majority of beam is within the allowed alignment then the car will pass but there could still be a problem with oncoming glare.
So Jonvella, you better start saving your pennies up for the real thing, me too i think :eusa-think:
