How to adjust the lens tangent correctly?Does the lens tangent two z coincide?

First of all, it is best not to completely overlap the two Z of the lens tangents. If they overlap, the light will be concentrated on one point, which will greatly shorten the width of the illuminated light. Under normal circumstances, when the left and right headlights are not aligned, the light emitted by the headlight lens is Z-shaped. At this time, the left and right lenses must be adjusted.

Generally speaking, the upper and lower height and the left and right width of the lens can be adjusted, so the correct way to adjust the lens tangent is to keep the tangents of the left and right lenses aligned, and there are basically no specific requirements for the upper and lower height. As long as it does not obstruct the car in the opposite lane, and the light is within its own visible range.

How to adjust the headlight lens?

The headlight lens is mainly adjusted by the headlight adjustment screw, so find the position of the adjustment screw first. You need to open the engine compartment cover to find it, probably near the edge of the car lights. The normal headlight adjustment screws are all toothed around, the center is an inner hexagon or a cross screwdriver slot is added on the basis of the inner hexagon, and some screws are outer hexagon nuts, and riders can use this to judge .

After finding the position of the headlight adjustment screw, you can use a Torx screwdriver to adjust it. The headlight lens of general models can only adjust the up-and-down height and left-right width, but for some models, the low beam and high beam can be adjusted separately. This model has four adjustment screws. The rider can fine-tune each screw when adjusting, and then adjust the lens tangent according to the method mentioned above after knowing the role of the screw.

How to adjust the headlight lens to a suitable height?

At night, park the car at a position 7.6 meters away from the wall, and then draw lines at various positions on the wall, and adjust the height of the headlights according to the drawn position. A distance is the distance from the center of the low beam to the center axis of the vehicle, B is the distance from the center of the high beam to the center axis of the vehicle, and C is the distance from the center of the low beam to the ground.

In addition, if you feel that the above method of adjusting the height of the headlight lens is more complicated, you can also directly find a person with a height of about 180cm and let him stand on the wall. As long as the headlight is not higher than the position of its buttocks, fine-tuning can be made on this basis.
