Headlight Adjustment - Help Needed

After having new headlights (housings) installed, my headlights seems to be misaligned. Does anyone know how I can adjust them?

Thanks in advance!

At the back of the headlights there are two screws that adjust the headlight height and left to right. You have to park the car right in front of a wall, and mark the current location of the light beams on the wall. Pull back 20 feet and then move the screws until they line up right. Just google headlight adjustment and you'll see videos and step by step instructions.
