Interesting rule change! Of course, fitting LED bulbs does not necessarily equate to dazzling headlights, as a well engineered LED device would replicate, or better, the bulb it is intended to replace. I have Philips LED bulbs in my kit which, although bright, easily met the criteria of no light in the dazzle zone in previous MOTs. Actually, the tester noted that the horizontal cut-off was way better than that of H4 filament bulbs in similar headlights. I believe the burning question is: what dictates an "existing halogen headlamp unit"?
