How to adjust the low beam of King Kong dump truck?

Adjust the left knob up by two gears to become the low beam gear.

Adjust the left knob to the "off" position to turn off the headlight position, adjust the left knob to the position shown below as the width light position, adjust the middle knob to the position shown below as the rear fog light position, rotate the control lever up or down as the turn signal position, rotate the control lever backward by one position as the single high beam position, and forward as the constant high beam position. In addition, the height of the low beam lamp can be adjusted.

Generally speaking, the adjustment standard of automobile low beam lamp only stipulates the light intensity and beam irradiation height. The low beam lamp should illuminate the position 25-35 meters away from the front of the car, and its beam height should not be too high, which is easy to sway to other cars and affect driving safety. The low beam of the car can be adjusted by the knob behind the headlight assembly with tools. Drive the car to a distance of 10 meter from the wall, measure the distance between the low beam and the central axis, the distance between the high beam and the central axis, and the distance between the low beam and the ground, then move it to the wall and mark it accordingly, and then observe whether the light of the car lamp deviates from the left and right, too high or too low. If the center of the headlight is not aligned with the marking point, it means there is deviation. You can adjust it by turning the headlight width adjustment button and aim the center of the headlight at the mark on the wall.
