Plastic adjustment knobs are on the backside of the headlight assemblies.
To do a "rough" alignment, you'll need a minimum level 25 foot roadway with
a wall to mark the beam target. First, pull the car up to the wall.
Measure where the center of the headlights are on the wall with some tape
"X" or other marking. Back the car straight back 25 feet, then using the
adjusters, aim the headlight beam so that it hits the X. You may want to
put a cardboard or cloth other the other beam while doing one side. Adjust
your foglights so that they hit lower than the X. This is just a rough, I
would strongly suggest that you have the actual job checked by a shop sooner
