The low beam dark/light edge should reach the floor at about 30m. This
makes a gradient of 60cm /30m assumig your lamp sits at hight 0.5 m.
Take a white stick and mark the edge directly at the lamp. Adjust the
lamps so that the egde is 2 cm lower at 1m. I used to do it with a peg
in the pants.
Its a bit more difficult to get the beam centers both parallel to the car.
Test the results slowly approaching a white car in front of you at a
traffic light.
