On my last service at Ford I asked them to aim the headlights, thinking they would make the beam go higher (hard to see at night) but no, they made the beam go lower (damn apprentice). Anyway i want to fix the problem myself. I have to adjust the lights using the orange screw behind the lights, right? How high can the beam be? 1/2 meter? Any advice on adjusting the lights would be great. Thanks.
