Good suggestion, but that's not it. There are no etched cut off lines on the glass in front of the low beam reflector, the glass is completely clear. Even if replacement headlights had been incorrectly sourced for a Left Hand drive model, this doesn't explain why the white nylon headlight adjusting screws make no difference to the point of aim when turned both clockwise and anti-clockwise on both headlights.
