There is a good article in this issie of ADI NEWS, regardign the alarming trend of illegally fitted
HID bulbs in headlamp units not designed for it.
The bottom line is that it
is illegel to retro-fit the lamps. As the housing/reflector is not designed for that kind of lamp, it scatters the beam so it no longer falls within the guidlines.
Then there's the whole problem of no washers, and no leveling system.
Worryingly, a whole goup of suppliers were questioned by as if from a potential buyer, and all of the advice given was just plain wrong and illegal.
The moral of the story? Don't try it, it will fail an MOT and is dangerous.
If anybody is interested in reading it, I will scan it and post it up here.
