Due to various reasons, the brightness of car headlights will gradually decrease, and the lampshade of the headlights will age. As a result, the brightness of the headlights will decrease by at least 50%. The blurry light tubes not only cause dizziness, but also can easily cause traffic accidents at night. Therefore, car headlights should be regularly inspected and the brightness of the headlights should be adjusted.
The staff of the vehicle inspection center explained: "During the annual inspection of vehicles, the position of the light beam will be checked to see if it is correct." The correct position of the light beam will make the night driving vision clearer and safer. When there is a problem with the car lights, it is not necessary to go to the 4S store to make adjustments. You can also do it yourself.
Four steps for adjusting the brightness of car headlights:
Step 1: When the position of the car light beam is incorrect, choose a dimly lit environment, underground parking lot or at night, and face the front of the car directly to a wall. The front of the car and the wall must be aligned and separated by five or six meters.
Step 2: Turn on the car lights, cover one of them with a thick, opaque cloth, and adjust one headlight separately.
Step 3: To ensure that the headlight beam is in the normal driving position, you can find someone to sit in the driver's seat.
Step 4: Mark the center of the light range on the wall with a marker or chalk, and also make a mark on the wall corresponding to the center of the front of the car (logo) position. Adjust according to the mark.
