The third adjuster is for right/left angle. Sounds is if you are WAY off (not shocking).

If you cannot adjust the lamps with a guage or with the correct measurements on a wall at 25 ft, the best thing to do is find a long driveway or quiet stretch of level road where you can fiddle about for a while. Cover one headlamp (or unplug it), then adjust the high beam so that the main part of the brightest part of the beam contact the road about 50 yards out or closer -- unless you are coon hunting, it's the road you want to see, not the trees or the planes overhead. The bright area should be centered in front of the car, not the center of the road, so that oncoming drivers can see, too. Low beams will then be pretty much OK. Don't try to do this with both lamps shining on the road, it's nearly impossible to tell which one is where.

The better prodecure is to find a level spot 25 ft from a vertical wall. Measure the headlight height on the car, and mark the wall at that height in front of both beams. Mark the spot on that line exactly in front of the headlight. Set the high beam so that the bright portion of the beam is just to the right and below the mark. Should be just about perfect.

You can see better with the headlight aimed straight ahead, but no one coming the other way will be able to see diddly from teh glare.
