Do you want to know how to adjust them mechanically or how they should be aimed at the road? To adjust the headlights open the hood and look just above the headlight and to the outer side, you will see some torx head bolts, the one on top is up and down , and the one on the side will be right to left, IIRC. There is a procedure you can use by parking so many feet away from a wall and measuring the center of the light beam, if you Google headlight adjustment you will find it. But I just parked on a dark country road and got out of the truck and adjusted them by looking at the beam. Just takes a couple min. PM me with any ?
