On more than a few occasions, I have had other motorists trying to tell me that my lights are on high beam., they were not. However I have noticed that whilst following other vehicles, the beam does appear high on their cars rear. I understand that with self levelling suspension, I have no adjustment. Any thoughts please. 2013 SDV8 4.4 SE Luxor.
1960 Series 2 88 inch diesel.
1955 Series 1 86 inch petrol.

The basic alignment IS adjustable, self levelling suspension means the alignment doesn't change (much) as the vehicle is loaded.

There are two white adjusters on the headlamp unit, IIRC the top one is for height adjustment.
