Even if adjusted properly, if you have heavy loads / loads in the back of the vehicle or when you are towing, etc., your headlight beams end up projecting higher..
It's easy to adjust your JL/JLU/JT headlights..
Re-aiming your JL's headlights is easy easy to do yourself. It takes but a few minutes to do and there are no special tools involved..
Hint.... with 2 small colored Sharpie marks/dots, mark on each adjuster. Mark your stock adjustment / factory adjustment. This way you have lets say a starting point to use, if / and when you need it..
Example, you go back to stock tires, you get the adjustments way out of wack, you adjust only when you are towing that frigging trailer.....
........with any of the aforementioned, you can then get back to the stock adjustment quickly thanks to your Sharpie marks.
