what to set the headlights on Merc 814 to the proper setting?

I don't know the setting ,there should be a sticker on the vehicle with the setting ,if not then a test station if any are still open can adjust them...If it's because you need to know for test ,then you can adjust them at test ..worse case is you get a PRS which basically means you did a minor repair during test as long as everthing else is ok you still get a pass
