you can also update your Signature, otherwise you may be confusing a lot of folks who jump into these forums from the right hand column, not understanding that you are now talking about a Legacy diesel pusher...
We had similar issue with our '18 Legacy 38C with the headlights pointed what felt like straight down. Took it to local Freightliner and they adjusted them for free. Now we can actually see what is in front of us while driving.
I have a 15 legacy, there is an adjustment for up and down on the headlight. It’s a plastic screw on the back of the headlight assembly that takes an Allen wrench. You can get to it through the generator compartment or by coming up underneath. If you can park it about 20 feet from a wall, turn on the lights and mark where they are hitting with masking tape. You can then adjust them up a little if necessary. I never got mine to work very well. When I adjusted the low beam to hit 50-75 feet In Front of the coach, the high beams were lighting the tree tops. Turning on the fog lights for all night driving helps.
