Speaking of "car lights"
Is lighting the first thing that comes to mind?
Actually used for lighting
Only high and low beam lights
The function of other car lights is more warning.
So how to use high and low beam lights correctly?
Can I turn on low beam headlights when driving on the highway during the day?
Are daytime running lights for good looks or for safety?
Low beam lights are used for close-range lighting in the direction of vehicle travel. The illumination distance is generally about thirty or forty meters. They are the most commonly used lights when driving at night and when visibility is reduced.
High beams are generally used when driving on highways, suburbs and other roads without street lights. The light of the high beams is emitted in parallel and the brightness is relatively large. The illumination distance can reach about 80 meters to 120 meters. In the dark, Turning on high beams on the road allows drivers to see farther.
Editor's reminder
High beams are very useful
However, misuse can easily lead to accidents

Dazzling high beam lights can cause instant blindness
The luminous intensity of high-beam headlights is much higher than that of low-beam headlights, which can cause oncoming vehicle drivers, cyclists, pedestrians, etc. to be dazzled and instantly blinded.
How dangerous is it?
Give a chestnut

High beams reduce the visibility of drivers of oncoming vehicles
The halo produced by high-beam headlights occupies a large area of human vision, reducing the visual range of drivers of oncoming vehicles. Experiments have shown that high beam lights can "cover" people and objects within 5 meters of the surrounding area. If there are people within this range, it will be difficult to see oncoming vehicles.
This is simply murder!

Abuse of high-beam headlights can easily lead to “road rage”
If a grumpy driver is illuminated by the high-beam headlights of an oncoming vehicle when meeting another car, he or she may respond in kind by shining the high-beam headlights back on the other vehicle, leading to irrational and dangerous driving behavior.

Using high beam when following a car will affect the driver of the car in front
If you use high beam when following a car at a close distance, a large area of reflective halo will appear in the interior and exterior rearview mirrors of the car in front, dazzling the driver of the car in front and making it difficult to observe the surrounding traffic environment.
It can be seen that misuse of high beam lights
How dangerous!
It's terrible to ignore this detail!
So, how to use high beam?
Next, I will explain it to you in detail.
In what situations cannot high beam be used?
▶When driving at night, do not use high beam lights on urban roads with good lighting conditions.
▶In principle, on roads with no street lights or poor lighting, when intersecting motor vehicles, non-motor vehicles and pedestrians, you should switch to low beam lights 150 meters away from oncoming vehicles or pedestrians.
▶When there are no street lights at night, poor lighting, or low visibility conditions such as fog, rain, snow, sand, etc., when following a car at a close distance, the car behind you cannot use high beams.
▶When encountering low-visibility weather such as dense fog, heavy rain, sand and dust, high beams cannot be used. If high beams are used at this time, diffuse reflection will easily occur, seriously affecting the driver's vision.
▶Do not use high beam lights when driving in highway service areas and toll stations at night.
When should high beams be used?
▶When driving on suburban roads or highways with no street lights or poor lighting at night, you can use high beam lights.
▶In some special circumstances, the high and low beam lights can be used alternately for signaling. For example, when overtaking at night, the left turn signal should be turned on in advance and the high and low beam lights or horn should be used alternately; when passing through sharp bends, slopes, arch bridges, crosswalks, or When there is no intersection controlled by traffic lights, high and low beam lights should be used alternately to indicate.
If you use high beam for an oncoming car, first pay attention to whether you have turned on the high beam unintentionally. At the same time, you can change the high and low beam to remind the other party. If the other party ignores the reminder, you should move your eyes to the right, slow down and drive to the right, and meet other vehicles cautiously;
If there is an intersection or complex road ahead, you should pull over and wait for oncoming traffic to pass before driving. If the car behind turns on the high beam, you can use the anti-glare rearview mirror, or tap the brakes a few times to alert the car behind you.
In addition to the correct use of high and low beam lights
in our daily driving
Car lights can also convey different code words
Do you understand it all?

Scenario 1: The headlights flash
Light language: The vehicle in front will not move after the green light is on, and the vehicle in front will be reminded.
Brief description: When waiting for a car at an intersection, when the green light is on but the car in front is not moving, we can flash our headlights to remind the car in front to move forward or give way to the lane. If there is still no movement, flash the headlights again. Do not flash the headlights continuously. This is disrespectful to people and can easily cause the driver of the car in front to become rebellious.
Scenario 2: Headlights flash twice
Lantern language: express dissatisfaction
Brief description: In many meeting situations, we will encounter a sudden strong light flashing into our eyes. This is most likely because the other party forgot to turn off the high beam. You can flash the headlights twice in a long distance before the meeting. Remind the other party to switch lights when meeting another car. If the other party is indifferent, the rider can show dissatisfaction by turning on the double-bounce lights and tell the other party, "You are flashing me, please switch to low beam."
Scenario 3: Headlights flash three times
Light language: Remind the vehicle ahead to check
Brief description: If we find that the door of the car in front is not closed properly, the taillight is burned, the tire is flat, etc., we can flash the headlights of the car in front three times to remind the car in front to stop and check the vehicle.
Scenario 4: Continuously flashing headlights
Light language: reject the merge request of the vehicle next to you or remind pedestrians or non-motor vehicles that they are on a motor vehicle lane
Brief description: When a vehicle changes lanes, if the two parties do not reach an invisible agreement, a collision or rear-end collision may easily occur. At this time, the vehicle changing lanes is often in front of the left or right side of the vehicle, so flashing the headlights is the most direct way to tell the other party whether you agree to the lane change. If we encounter the above situation, we should slow down and continuously flash our headlights to alert pedestrians or non-motor vehicle drivers.
Scenario 5: Brake lights turn on periodically
Light language: Don’t follow the car too closely
Brief description: When driving on the highway, maintaining an appropriate safe distance is an effective way to avoid accidents. However, some people like to follow cars at high speeds and keep a relatively close distance. In this case, the driver of the car in front will definitely Distract part of your energy to "pay attention" to the car behind you, and you will inevitably have to worry about whether the car behind you will hit you because you didn't brake in time. At this time, the car in front must find a way to give a warning to the car behind, telling the car behind not to follow it closely. At this time, the brake light must be used. When driving on the highway, the brake light is used in another way. When the car behind is too close to your own car, the driver of the car in front can lightly apply the brakes to remind the car behind "You are too close to me, you should stay away." ".
Scenario 6: Flash the headlights three times and honk the horn
Light language: Be careful when entering or exiting alleys or blind spots.
Brief description: Alleys are prone to visual blind spots. Drivers who need to enter alley entrances are advised to flash their headlights three times. To remind oncoming vehicles or pedestrians to pay attention. Some drivers like to turn on high beam when entering alleys or alleys, thinking that it can serve as a warning. In fact, this idea is wrong because many pedestrians or drivers cannot judge distance by light. Therefore, the flash reminder is far more effective than the high beam.
Scenario 7: Three high beams plus double flashes
Lantern language: emergency help
Brief description: Use three high beams and double flashes to create a sense of crisis. At this time, vehicles with conditions for rescue will lend a helping hand. This advantage is easy to operate and has a wide delivery range. At least there is no need to paint a big "SOS" with paint.
