When adjusting E code lights , you do not adjust the high beams. You adjust the low beam so that the cut-off line is 2-3 inchs below the headlamp height at the car. This is on a wall at a distance of approx 25 feet.
You then adjust the rising angle starting point intersection
[ where it starts to rise to the right from the cut-off line on LHD vehicles] at dead ahead of the headlamp measurement at the car.

An easy way to mark the wall is to place a piece of tape at midpoint on the rear window . Square the car to the wall at 25 feet . Looking from the rear of the car , sight the tape using the hood emblem star like a rifle sight. That is the cars mid-point vert. line on the wall.
Now measure the distance of the car headlamps from the ground . [Measure from the center of the relector]. Deduct 2-3 inchs from this and mark the wall with this horiz line.
Now measure the distance from headlamp to headlamp on the car . Divide that by two and use that measure on each side of the vert line on the wall, marking the distance on the horz- line. These 2 marks are where the cut-off line height should be adjusted to and also
where the beams right rising angle should originate.
For accuracy, use your dominate eye for tape/emblem sighting

PS -- Proper tire pressure and tank of gas [ie. load] give best results....
