The Euro lights have a four pointed star shaped adjustment knob for vertical and another for horizontal. One will be down low and hard to see.

If nothing is happening when you turn it one way, turn it the other. When it reaches the end of its range it will not move the light beam.

If you have the owners manual, there should be a detailed adjustment instruction. It will involve positioning the car in front of a wall that you can mark with chalk or something.

Good luck,
