Hello everyone. I screwed my headlights. I wanted to adjust the headlight low beams. I've attached two pictures of the right unit to show you the two screws that I used to adjust the level of the light. Well after a bit rotating the thing happened - it stopped adjusting the level and my lights are very low right now. The screws are still rotating but the unit is not responding. What I need to do to fix this? I hope you understand me, because my English is very BAD.
