I installed these perfectly and i noticed that my right beam is aiming a bit higher. I found what i think the knobs were on the back. They're greyish with a cross or plus sign in the middle. I thought i had to put a screw driver in it to turn and adjust the beam light. Didn't work. I also tried turning the knob which was really tough. Didnt work either? I dont know how to adjust these.
I email the company and the guy said there should be 2 knobs at the back of the headlight. But never responded after that.
These are the headlights
