2012 ML Headlamps Swap?

The advertising blurb says they are BiXenon, which is untrue!
The W164 did have BiXenon and they were simply brilliant.
The W166 has a single Xenon globe for low beam, with a mechanical reflector that deflects some light upwards for high beam.
Result - excellent low beam with good spread, but high beam is patchy with limited extra visibility.

If you only drive in the city then you will be happy, but hit the rural/country roads and you will suffer. My next step is to see if I can connect external driving lights.
Also the auto dimming lights are useless. Continually going up and down when the see white posts on the roadside, and not dipping until the oncoming car flashes me. I now always manually use high beam.

These lights have been my only complaint for the dealer in 24,000km. And they report everything is normal?
