1995 Legacy.  Bought some new headlights last week, installed them 2 days ago and could not adjust them vertically.  Said screw it, pulled them and reinstalled the originals.  Today began to think I may have been trying to lower them using the wrong adjustment screw.  Which of the 2 screws adjusts vertically or which one adjusts left to right?

 

I have been humbled. Defeated by a headlight.

Pull your car about 4 feet away from f flat wall and straight ahead.  Turn on the lights and start cranking the two adjusters.  You will see the beam move.  As you move the left to right adjuster to move the light beam in or out it will also adjust the vertical some due to the design.  Inner lower adjuster is for in and out.  Top adjuster is for up and down.  As you move one it does affect the other some.

A good place to do this is to shine the head lights onto a closed garage door, when it is close to getting dark. That way it is easy to see what adjustments you are making.
