Have you ever been out driving and noticed your headlights were shining in the tree tops!
Believe it or not headlight adjustment is not typically an issue. Back in the day, I had to use a foot long Philips screwdriver. We used a device that sunctioned onto the headlights to help make the correct adjustment. The long screwdriver was required to reach the and make the adjustments. We used the device that had level bubbles inside it to make the adjustments.
Pa Inspection shops are required to have a chart to adjust your headlights but you can take a good guess at home. There is typically an adjustment at the top/center and the left or right of your headlight. And Most likely the screwdriver needs to be a “torx” type end to make the adjustment. Do not be surprised if the adjust screw is rusted in place. the adjustment is usually in plastic, but can be difficult to get to and turn.
