Headlight adjustment height? How to adjust the height of the headlights of the car

Step 1: First, find a site with a horizontal ground and vertical white walls in the underground parking lot. Facing the white wall, drive the car straight and slowly, and stop the front of the car as close to the wall as possible.

Draw a vertical line on the wall corresponding to the position of the center line of the front of the car (for "mm", which is the center point of the head mark of the middle grid) (note: in order to avoid painting other people's walls, I recommend sticking it with tape to facilitate removal). Then, reverse in a straight line and stop at 25 feet (i.e., about a meter) of the headlights from the wall

Step 2: Take the following two measurements: Measure a: Measure the height from the geometric center point of the headlight cover to the ground Measure b:

The distance from the center point of the low beam lens to the center point of the front of the car (in the case of "mm", the center point of the car logo of the center grille), and the distance from the center point of the high beam to the center point of the front of the car.

Step 3: On the wall, draw two horizontal lines (which can be replaced by adhesive tape), one corresponding to the measurement A value in step 2, which is the height from the center of the headlamp to the ground, and the other is 2 inches (about 5 cm) lower than the height above. Then, according to the measurement B value in step 2, according to the distance between the low beam and the high beam to the center line of the front of the vehicle, from the center line of the wall, the position of the low beam is marked on the lower horizontal line with a short vertical line, and the position of the high beam is marked on the higher horizontal line.

In this way, four crosses are formed on the wall, the lower two corresponding to the center of the low beam dividing line, and the upper two corresponding to the center of the high beam.

Step 4: (a) Low beam adjustment: Before adjustment, turn on the low beam, at this time, the light and dark dividing line will be projected on the wall, according to the legend below, use a cross wire cutter to pass the left and right and height adjustment screws of the low beam to align the position of the center turning point of the low beam dividing line with the low beam sign on the wall.

When adjusting, the left and right low beams are adjusted separately, and when adjusting one side of the low beam, the other side of the car light should be blocked.

Step 5: (b) High Beam Adjustment Turn on the high beam, and also use the hexagon socket to adjust the height of the high beam and the left and right adjustment screws. Since the high beam has no cutting line and is projected on the wall with two spots, adjust the center point (i.e. the brightest spot) of the high beam spot to the high beam sign on the wall.

If you are dazzled and can't distinguish the center of the high beam, it is recommended to wear sunglasses to see it, so that the contrast between light and dark is obvious. ‍

How do I adjust the height of my car headlights? Many car owners don't know this button and waste it in vain.

Method 1: Most cars now have "highly adjustable headlights" with a high adjustment button in the cab.

Turn it up, the lights go out; Turn off the lights and the lights are on. Sitting in the driver's seat and turning the button to look at the light, you can see the obvious change, and the operation is simple. This button can control the front and rear headlights at the same time.

Method 2: Adjust the light button of the headlamp assembly.

A few models don't have a "height adjustment" function, and there is no height adjustment button on the headlights, and the fine adjustment button on the headlights is a yes.

In general, ordinary passengers adjust the height of the headlights, adjust the height of the cab of the adjustment button, and there is no adjustment button that needs to be adjusted, the headlight assembly; Unless there is an adjustment on the other side of her replacement with a new fitting, and the height gap in the old lamp is too large, otherwise there is not a button in the headlight assembly.

Adjustment tool: Allen wrench.

Most headlights are controlled by an Allen nut, and an Allen wrench is used to adjust the Allen nut. Adjust the hex nut so that the headlights are at the same height.

Adjustment method:1. Adjust the height left and right.

Whether adjusting the buttons in the cab or adjusting the nuts on the headlight head with a hex wrench, the wall must be adjusted to the wall.

First, choose a plane with the head of the wall five meters away from the wall and the body perpendicular to the plane angle of the wall. Look at the left and right sides are the same height, and the right side can be a little higher than the left side. If the right side is lower than the left side, you can use an Allen wrench to adjust the adjustment nut on the right side of the headlamp assembly.

Adjust the headlight illumination distance.

The next step is to adjust the distance of the light, adjusting the height of both headlights at the same time.

Drive the car into a flat, open space and measure a distance of 30 meters. A beam of almost 30 meters away is basically suitable. If you adjust it too high and too far, it will affect the driver's line of sight.

Headlights are not the same. If the light is 30 meters high, the high beam is too high, so the light and low beam can be lowered.

As an affectionate car mechanic, I often receive all kinds of private messages and questions from car friends. I also use my spare time to answer private messages from riders. In addition to answering the private messages of car friends, I saw the question "How to adjust the height of the headlights?" ”

There are two ways to adjust the illumination angle of the headlights, one is to adjust the headlight height adjustment button in the cab, and the other is to adjust the rotary button in the headlight assembly, which is discussed as follows

1. Method 1: Rotate the headlight height adjustment button in the car

Nowadays, most cars have the "headlight height adjustable" function, and there is a headlight height adjustment button in the cab, as shown below

The button in the red circle in the figure is the headlight height adjustment button, which rotates up and the light irradiation height downward; Rotate downwards and the light shines upwards.

Sitting in the driver's seat and watching the lights while rotating the button, you can see the obvious changes, and the operation is simple.

But it should be noted that this button controls the left and right headlights at the same time, if you need to adjust the left or right side separately, or some cars do not have the "headlight height adjustable" function, there is no headlight height adjustment button, you have to use the second method.

2. Method 2: Adjust the fine-tuning button of the headlight assembly.

A small number of models do not have the "headlight height adjustable" function, and there is no headlight height adjustment button, but the fine-tuning button on the headlight assembly must be there, as shown in the following figure:

The two white buttons circled in the red circle in the picture above are the fine-tuning buttons, and you can see the change of light shape by rotating and twisting with an Allen wrench.

Generally speaking, ordinary riders want to adjust the height of the headlights, adjust the height adjustment button in the cab, there is no need to adjust the fine-tuning button on the headlight assembly; Unless there is a new assembly on one side, and the difference between the height of the light shape and the old one on the other side is too large, you have to adjust the new one, otherwise you don't need to move the button on the headlight assembly.

The buttons on the headlight assembly only play a fine-tuning role, and the adjustment amplitude is not too large. Moreover, it cannot be operated roughly, so as not to damage the headlight assembly.

Answer: For the adjustment standard of automobile low beam, generally only the light intensity and beam irradiation height are specified, and the low beam should illuminate the position of 25-35 meters from the front of the car in front of the car, and the beam height should not be too high, which is easy to shake to other cars and affect driving safety.

Automotive low beam adjustment standard.

The car low beam can be adjusted by the knob at the rear of the headlight assembly with a tool. Drive the car to 10 meters away from the wall, and measure the distance from the low beam of the car to the central axis, the distance from the high beam to the central axis, and the distance from the low beam to the ground; Then move to the wall and make the corresponding marks on the wall; Then observe whether the light line is offset from side to side, too high or too low, if the headlight center is not aligned with the marking point, it indicates that there is an offset, which can be adjusted by rotating the headlight width adjustment knob, and the headlight center can be aligned with the mark on the wall.

Generally, the width of the lights has been set at the factory, and it is not recommended to adjust it yourself. If there is an offset, you can fine-tune it, and you can adjust the right car light beam slightly to the right when adjusting, so that you can see the right side of the road more clearly in rainy or foggy days with low visibility, but it is more recommended to go to a 4S shop or repair shop to adjust the specifications.

The specific operation steps are as follows: Press the brake pedal of the car to turn on the power supply of the whole car. Press the vehicle's one-button start button. The vehicle's instrument panel lights up and the entire vehicle is powered on.

Twist the headlight switch until the headlight is on. Roll the headlights to adjust the rollers, scroll up the headlights up, and scroll down to lower the headlights.

How do I adjust the height of my headlights?

Open the front hood, there are several holes directly above the two headlights, the outer side is the knob to adjust the height of the headlight, the inner side is to adjust the left and right, you can see from the top that you can see that the inner side with a funnel-shaped Phillips screw is to adjust the left and right of the headlight, and the compass-shaped knob on the outside is like a vertical compass to adjust the height of the headlight, which can be touched by hand. The "funnel" can be rotated clockwise on the inside to expand the light outward and retract counterclockwise; Rotate the Compass clockwise on the outside to turn the light up, or counterclockwise to turn it down.

Hello 1, find a wall, make sure the ground is level, park the car at a distance of about 10 meters from the front of the wall.

2. Measure the height from the ground to the center of the headlights, and measure the distance between the two headlights.

3. Post a horizontal masking tape on the wall that is one meter lower than the headlight, and make sure that the tape is directly in front of the car.

4. Turn on the headlights.

5. Adjust the vertical adjustment screws until the headlight beam is in the middle of the tape on the wall.

6. Continue to adjust the vertical adjustment screws until the headlight beam is straight forward, in order to ensure the correctness of the adjustment, measure the height of the beam on the wall and the height of the headlight, and ensure that the values of the two are equal.

After the adjustment, sit in the car and look at the following, and the adjustment of the headlights is over.

There are two ways to adjust the height of the headlights: He Chan shouts

1. The first one, there is a headlight height adjustment button in the cab in the car, rotate up, the light irradiation height goes down, rotates down, the light irradiation height goes up, sits in the driver's seat, and observes the light while rotating the button, you can see obvious changes, and the operation is simple;

2. This button controls the left and right headlights at the same time, if you need to adjust the left or right side separately, you need to use the second method;

3. In the second method, there are two round threads that are stretched in with a Phillips screwdriver behind the headlights, one is adjusted to the height, and the other is to adjust the distance.

Headlight height adjustment method: 1. First park the car at a distance of meters from the wall, and then turn on the light, and then we will adjust the illumination position of the light according to the position of the light on the wall. If the model with the headlight adjustment switch needs to adjust the height manually, then the headlight height adjustment knob should be adjusted to the "0" position before adjusting the headlight; 2. In order to set these standard lines on the wall, we need to measure the three distances of the headlight position of the car in advance, and the distance A is the distance from the center of the low beam to the axis of the car; Distance b is the distance from the center of the high beam to the center axis of the vehicle; Distance c is the distance from the center of the low beam to the ground; 3. Adjusting the position of the light is achieved by adjusting the knob of the corresponding position behind the headlight.

The parts that need to be adjusted and the tools used vary from model to model, depending on the model. Before adjusting, first hit the headlights on the wall, and then look at the vertical to see if the lights are offset or too high or low; 4. If you think this is difficult, then the easier way to judge is to let a person with a height of 180cm stand in front of the car, and then the low beam relationship should not be higher than the person's buttocks. If it is too high, then twist the adjustment knob to adjust.

The height of the headlights can be adjusted: 1. The height of the headlights can be adjusted, which means that the height of the headlights can be adjusted in order to obtain the best illumination distance to avoid danger. This is a safety lamp configuration, which generally uses an electric motor to adjust the height of the headlights through electric means, so as to obtain the best irradiation distance and avoid danger while driving;

2. According to the adjustment mode, it is usually divided into two types of adjustment: manual and automatic. Manual adjustment: The driver controls the headlight illumination angle by turning the wheel of the interior light adjustment wheel according to the road conditions, such as adjusting to a low angle when going uphill and a high angle when going downhill;

3. Automatic adjustment: The body of the leather car with the function of automatic light adjustment is equipped with several sensors, which can detect the dynamic balance of the vehicle and automatically adjust the lighting angle through the pre-set program;

4. The headlight height is adjustable, generally in the interior of the car, there is a manual selling lack adjustment knob, you can adjust the illumination height of the headlights at will, but the headlights of some high-end luxury cars are automatically adjusted horizontally, although there is no manually adjustable button, but the vehicle can automatically adjust the height of the headlights according to the relevant sensors.

Millions of car purchase subsidies.

Generally, there is a number like 0123, which is the electronic shed adjustment gear of the headlight height. The general number 0 is the lowest, and 3 is the highest:

1. Therefore, when the car is empty and empty, it can be adjusted to 0, and the car is pressed and sinks violently, and the light line of course will also fall, so it can be adjusted to 3, and the light angle will be pulled up;

2. The same is true of the 123 in the middle. How much load is on the car, how much the chassis of the car sinks and how much the cover goes down, it is adjusted according to this;

3. In fact, it is very easy to understand, for example, when the car is empty, the car must be in the highest position (the chassis is the highest), the car is fully loaded, full of people, and stuffed with luggage, the car must be pressed and sunk (the chassis sinks to the lowest).
