- With regard to vertical modification, you will have to use the screw to try to position the upper end of the beam at the level of the horizontal marking on the wall, or slightly down below.
- Once finished, check that the headlights setting of your Alfa Romeo 159 is coherent, do not think twice to check it after you have driven it, oftentimes it may move.
