How to adjust headlights?
Have you located the two adjusting screws on each light? The are located behind the headlight door/trim that comes off with 4 screws. Some could be visible without removing the painted trim but I like to remove it so I do not slip and chip the paint.
One screw moves the light up and down.
The other screw moves the light left and right.
These movements are based on a tilting of the light and there is a spring behind the light bucket to keep them tight.
To get the right level, I normally park on a level street about 30 feet behind another average car. I adjust the low beam so it just misses (a bit lower)their mirrors. Right light should be almost straight forward, left light should angle a bit to the right to avoid blinding oncoming cars.
