What is that screw on allroad lights?

[Radoslaw Zatwarnicki]

Hi
My 2012 allroad has no adaptive, led or Xenon lights- as far as I'm aware.
Will be traveling trough Europe soon and noticed this screw.
Is it some sort of manual regulation? Or do I still need stickers?
Thanks

Is that for height or left/right regulation?
Thx
