Well, there IS an old -fashioned way to adjust the headlights.
1. You go to Dusseldorf and get a barrel of ALTBIER...and put it in the back of
the UNIMOG.
2. You mount up your PTO WURST-SLICER on the front and get some of your favorite dried sausages standing by,
Then you wait until it is dark, but in the meantime you guess how much Bier you should remove from the barrel to lower the headlights, and how much sausage you should remove from the front table to raise the headlights, and
by the time it is dark, you'll find that you think that the headlights are just fine right where they are, and you can leave it parked and head off to solve other
problems. I'm not sure it works with the SBU's.
Mercedes had this as on option for the 123 diesel wagons, not sure if it was available in the USA. I had it on my last 300TDT, the previous owner had bought it from over seas and retro fitted it. It relied on engine vacuum (like EVERYTHING else in the car) to power the lights up and down. There was a dial on the dash to manually adjust the lights up and down, It also had a line plumbed into the rear SLS (self leveling shock) system that pumped up the rear shocks when you threw 300 lbs of wet german shepherds in back. I imagine that it was to have the headlight aim automatically compensate for heavy loads. Sadly the car was stolen, so I can't go get all greasy looking. I imagine that the engineering for both systems is similar, at least it sounds so.
Edit: headlight aiming option, not the wurst slicer. Just had to clarify

So , I fired the U1450L up last night and thought I'd check the function of the headlight aiming knob...the UNIMOG came up to air pressure, and I could not get any movement out of it, with the headlights shining on a wall....then I drove it around for a while and thought I'd try it again...and it worked as it should.
I don't know where the air pressure was hanging out in the meantime, but
you might re-check yours after driving it a bit...it worked for me.
They are hydraulically operated. Do not ask how I know and how much I paid for a replacement set. They move little pistons in the headlights so the lights move up and down.

So... only trucks with hydraulics can have them? Or do they have their own electric-hydraulic system so any Unimog can have that (L35) option? I believe you....I sure don't know otherwise.
