Is the dipped beam also blind? 3 minutes to teach you to adjust the lamp height!

I don’t know if you’ve ever had the experience of driving at night with the low beam light on, but the opposite car still flashes the light twice to indicate that you are driving the high beam light.
Maybe there is something wrong with your light.
The height of car lights is adjusted when leaving the factory. Generally, there is no big problem. However, if your headlights have been repaired or replaced, the height of lights may be inaccurate.
If the height is too high, there will be a high beam effect. If the height is too low, the visibility at night will be very low, seriously affecting safety.
So, what exactly is the height of the headlights?
First, find your lamp adjustment button.

The headlight height adjustment button is usually installed behind the headlight assembly. We need to open the hood and find this small rotatable button.
What should we do before adjusting the height of the headlights?
Before adjustment, we need to ensure that there is no one in the car, and if there are any heavy objects, we need to take them away to prevent the car body from sinking and affecting the accuracy of height adjustment.
Some steering wheels are equipped with lamp height adjustment knobs, so it is necessary to reset the gear first and find a smooth road surface with walls, even underground garages. Take a tape measure, measure the dipped beam and record its height. Then mark the same height on the wall, both sides.

The marked position is the installation height of the headlight as the reference standard for adjustment. After marking, we can start the car, turn on the dipped beam, and let the car be within 3-10 meters of the wall surface, on the premise of clearly seeing the light-dark boundary.
After the preparatory work is completed, the adjustment will begin.

When adjusting the height of the lamp, it is necessary to ensure that the height of the dipped beam lamp is not higher than the installation height of the lamp, and marks have been made on the wall surface before, so we adjust the light-dark dividing line of the lamp to be not higher than the marks.
The low beam lamp should be left low and right hight, and the left low and right high refers to the left low and right high of the lamp shape, i.e. “asymmetric low beam forward illumination system”. Therefore, we still need to ensure that the left and right lights are at the same height when adjusting.

If the high beam is split and needs to be adjusted separately, the method is the same. However, the high beam is a relatively large spot and there will be no clear light-dark boundary, as long as the center of the spot is aligned with the installation height of the high beam.
