The horizontal RR line is carried out at the height equal to distance of N — height of the centers of headlights. Below the RR line the horizontal lines passing to the right of lines V—V to inclined lines, a tilt angle are put on size K on the left side from the RR line 15 °. Thus broken lines C are formed — S.Velichina K is equal to standard shift of horizontal light-to-dark border of a bunch of a passing beam. At adjustment and check of force of light of one headlight another close an opaque zaslonka.
