Adjust headlights: How to do it right.

Hi,

I am familiar with the vertical adjustment of the headlights. In my Golf III, the adjustment is 1.2° (Hella headlights with a Golf IV look). Therefore, at a distance of 10 meters, the boundary between the bright and dark areas must be 12 cm lower than the height from the (level) ground to the center of the headlight.

But what about the horizontal alignment? Do both headlights need to shine perfectly straight ahead, or are there any deviations that need to be considered?

Hi,
The points where the asymmetric low beam headlight bends must be perfectly straight.

You're welcome.
