Can anyone help me? Is it possible to adjust the main beam on the headlights without altering the position of the dipped beam? I cant get a good balance on mine! when the dipped headlights are in a perfect position the main beams are pointing three feet in front of the car and when i have got the main beams adjusted to an ideal position the dipped lights are lighting up the tops of trees. I have tried manual adjustment with the white wheel but both lights seem to move together. Any ideas?
