Had issues while driving at night for quite a while, the bulbs are fine and the headlights are clear. While doing research, Hella and Champion Auto Parts seem to have the most technical way for headlight adjustment. However, there weren't any flat walls around, so I decided to make an instrument for adjusting headlights. I made sure the fuel tank was half filled with the recommended tire pressure.
They're simply pot stands with A4 papers attached to tape, made sure the papers are as flat as possible. And scaled up to 80cm in height. Both involve two mask tapes, one for the headlight, and another for the fog lamp.
Did made sure the mask tapes were aligned with the dots. The fog lamp didn't have one, so I made sure the masking tape was as centered on the foglight as possible.
A forward inclination of 1.3% means that the low beam is at an angle of 13 cm at a range of 10 m. Both headlights have the same percentage. There was no forward inclination for fog lamps, so I followed 2% as a standard from Hella.

The final adjustment.
Moved the car back 10 m with the help of a 10 m power adapter. And a companion was sitting in the driver-side of the car. The right one is a little low, but the left one is way high.
After the adjustment. One issue I did face it was difficult to see the cut-off lines due to the instrument's limited width.

Not the best location for testing, but just for reference. But it felt much better and safer while driving on the road.
