If the headlight is installed by the left and right fixing screws, just loosen the screws and pull the headlight up and down to adjust the height. Others cannot be adjusted. Just pretend you are something.
If the light of the battery car is not focused, you can add a lens. If it is too close, you can adjust the angle. Or you can buy an LED with a focusing lens. If the LED is out of focus, stupid and bright, the other party will feel dazzling. If you can't see the road clearly from the owner's side, it is easy to go wrong if the pavement effect is not good, or you can install LED spotlights.
