Ian,
Out of interest, if beam shape and light output is compliant on the MOT test machine, does it matter what created the light?
For example, would it matter if the slight ource were, candle, gas lamp, incandescent filament, HV discharge or indeed LED?
Or, do the agencies have a bee in their bonnet that the physics of HID alone is evil and will kill all children if headlamp levelling and wash are not used to tame that devil?
Sorry if I appear facetious but it winds me up that people automatically assume that HID = headlamp levelling and wash, as my contention is that a bulb is a bulb no matter what is powering it, as long as the light output is shaped by a mask.
I must add that I am not an apologist for people who misuse HID "kits" by installing them in non-projector headlamp units...
