@Woodman77 Woody, there is a few ways people do this, so you might get a few different ways posted, but they are all a means to the same end. You need flat ground, and a wall, preferably a light colored wall.
You want to measure 20' off the wall.
Now you can either park so your front bumper is at the 20' mark and measure the height from the ground to the center of your headlights and then transfer that height to the wall, or you can pull up close to the wall so your bumper is inches from it, turn your lights on and mark the wall. you want the marks on the wall to look like big plus sign with the hottest spot in the middle, and then back up to the 20' mark. That's the method I like to use because because there is less a chance of making a mistake measuring and it takes into account any kind of abnormality in the headlight housing.
Then set the headlight beam so the center of the hot spot is just below the plus mark on the wall and the left headlight is slightly pointing to the right of the plus but the right headlight should be slightly lower than the plus but hit the plus right on side to side.
The principle behind the side to side adjustment is to reduce blinding the oncoming driver and reduce glare for you off the street signs.
Hopefully that helps and it's ok to tweak them a little if it doesn't look perfect going down the road at night, but the setup should put you really close to perfect.
