As the seasons change, the night becomes longer and the day becomes shorter and shorter. I used to go to the sun when I got off work, but now I have already gotten to the treetops when I get off work. When driving to and from work in such a season, you will have to face the night road every day. It is no wonder that recent reports on the abuse of high beam lights caused traffic accidents have increased. According to the statistics of the traffic police department, about 30% of accidents in nighttime traffic accidents are related to the abuse of high beam lights. Regarding the lights, will you use them correctly?
>>Abuse of the danger of high beam
Hazard 1: Instant blindness
When the car is going to be at night, the high beam light can cause instantaneous blinding to the driver. The blinding time varies according to the driver's own vision. The surrounding environment will have different durations, but the fastest time will last for about 2 seconds. In the two seconds, the driver is driving like a closed-eye, and the ability to observe the surrounding pedestrians and the incoming and outgoing vehicles is greatly reduced.
Hazard 2: Decreased perception of speed and distance
The line of sight at night is not good, so the human eye will have a discount on the speed of the opposite car. Under such circumstances, the interference of the high beam on the human eye will accelerate the judgment. When you turn on the high beam, you have misjudged your speed and distance to the car. You should slow down the car. He can safely avoid the bicycle or start overtaking. At this time, the high beam can be counterproductive.
Hazard 3: Decline in judgment on width
Similar to the above principle, the large halo produced by the high beam will occupy a large part of the area of ​​the human eye, which will make the judgment of the opposite driver's width on the vehicle and the situation behind it decrease. This may result in the wrong operation.
>>The correct usage of the lights
Highway driving
The sight at night is not good, and the speed should be slowed down appropriately. On the highway, there is generally no street light, so it is all illuminated by the lights. At this time, keep in mind the essentials of using the lights at night. Turn on the night lights and the width lights. If it rains or snows, turn on the fog lights. If there is no car in front, you can turn on the high beam normally. Just use the high beam to observe the road surface and the surrounding area at a distance, and then turn the low beam. If there is a car in front or there is a car on the opposite side, you must remember to turn the high beam into a low beam. Otherwise, the front or opposite driver's eyes will be shaken, which is not only annoying, but also easily affects yourself.
Country road driving
This kind of situation generally refers to county-level and township-level roads that do not divide the upper and lower lanes. Usually, there is no lighting at night or the lighting is seriously insufficient. In this case, it is almost possible not to use the high beam, but only the low beam. Because the design of the low beam is to illuminate the area within about 50 meters, the scene in this range can be seen relatively clearly with the low beam. The high beam is much higher than the low beam, and only a large distance can be seen. The blurred contour of the range object, while the near object is relatively inferior to the low beam.
In addition, if you must use the high beam, you must also use the low beam in the 150m range according to the regulations if there is no car in front and on the opposite side.
Urban road driving
Due to the strong street lighting system lighting, the driver can use the street lamp and the lamp to observe the road surface. The first two situations can have a clearer understanding of the road surface and surrounding objects. Make more timely and accurate judgments and treatments while driving.
However, due to the relatively complete urban lighting system, it is easy to cause the illusion that the lights have been turned on. As everyone knows, the visibility at night is higher, and the contrast between the vehicle and the environment cannot be reduced compared with the daytime. It is easy for other drivers to ignore their existence and cause an accident. Therefore, the lights should normally be turned on near dusk.
>>The use of various lights
Driving lights: indicating the size of the direction
The first gear of the light switch, at this time the instrument lights in the car are all lit, and the front and rear of the car will also light two small lights. The brightness of these two lights is not large, mainly to allow the four corners of the body to be seen. This light should be lit in dark places such as dark weather, rainy days or underground parking lots.
Low beam: relying on it at night
Use while driving in the city at night. On the one hand, the roads in the city have street lighting. There is no need for high-beam lights to explore the distant roads. Just look at the road conditions in front of the car. On the other hand, the traffic volume in the urban roads is large. Not only does the driver on the opposite side dazzle when the car is in use, but it also has an impact on the line of sight of the pedestrians on both sides of the road.
High beam: no need to use
It is more suitable to use the high beam in the wilderness or on the road without street lighting, but remember to change the low beam when you are in the car, so as not to dazzle the driver. When the high beam lights up, the blue light on the dashboard will illuminate as a reminder.
Turn signal: turn to remember to use it
The most basic use of the turn signal is to give other vehicles and passersby a turn signal when the vehicle turns to remind others. Sometimes the turn signal can also act as a lighting in a narrow place so that the driver can observe obstacles on both sides. When both sides of the turn signal are turned on at the same time, the warning and the width function are activated.
Fog Light: Bad Weather Helper
As the name implies, fog lights are the light signals used in heavy rain and fog. The fog lights are more penetrating in the fog, so it is easier for vehicles or pedestrians to notice early.
Reversing light: reduce the reversing blind spot
When reversing, there will be a white reversing light at the rear of the car. On the one hand, it can illuminate the road surface and obstacles at the rear of the car, and reduce the blind spot when reversing. On the other hand, it is also a reminder to the pedestrians at the rear.
>>Light adjustment DIY
Perhaps because of a minor accident, it is also possible that the screw of the fixed lamp has broken as the condition of the car deteriorates. In short, we may encounter a situation in which the angle of the lamp is suddenly out of alignment. This requires the owner to temporarily adjust the lights. Of course, after the event, the owner should send the car for repair as soon as possible. After all, the angle of the light that he adjusted is definitely not accurate.
There are two standards for adjusting the light. One is to illuminate the road ahead of the car. The other is that the angle of illumination is not too high to stimulate the opposite driver. In the absence of tools, adjust the headlights yourself, and certainly can't adjust according to the standard data. How do you judge? We can do this for how to determine the upper limit position of the low beam.
Using people as rulers
First of all, we can use people to make the ruler. For example, let an adult stand 2-3 meters away from the front of the car. The position of the light in the middle of the thigh is appropriate. If it is at the waist, it will be too high. Of course, everyone's height and leg ratio are different, so this can only be a rough standard.
Use the vehicle in front to make a ruler
We can observe the situation of the vehicle before the driving while driving. Let the vehicle be located behind the car and observe the position of the tangential line of the low beam. Make sure that the headlights will not shine on the rear windshield of the front car at any distance. Otherwise, it will affect the driving safety of the preceding car at night. Misunderstanding of the car in front of the car is swaying in the high beam, which is resentful. The lower limit position of the low beam should not be too particular, so that the road surface of about 20 meters in front can be seen.
Do not adjust the width of the light
The width of the light is set at the factory and it is not recommended to adjust it yourself. Because the low beam has a tangent in the high and low range, it is good to judge whether the position is suitable, but the range of the width of the light is wide, the boundary is also very blurred, and the feeling of the outside and the inside of the car is far from the difference, so It is impossible to judge a reasonable position when adjusting. If it is really due to collision or other reasons, the width of the light is not suitable, it is recommended to go to the 4S shop or repair shop for specification adjustment.
It is a small craft to adjust the height of the headlights by yourself. It can be used urgently in special circumstances. However, this is still a relatively poor adjustment method. It is recommended that the maintenance personnel check the position of the light when it is necessary to maintain the maintenance and repair of the vehicle.
