I replaced the passenger headlight housing on my S70 because of a stone chip and now the beam from that headlight hits the ground lower than the driver's side. That is, it is angled down such that it doesn't project as far outward as the other side does. There is a manual adjustment node the sticks outward, but I was tooling with it today and I could not get the level that is built into the housing to move at all. Which way do I turn the knob to angle the beam higher? And should the level that is built-in to the housing be moving at all?
