The high beam is one of the important functions on the car. Compared with the low beam, the light of the high beam is emitted in parallel. The light is concentrated and brighter. It can illuminate higher and farther objects. For nighttime The driver's line of sight helps a lot. However, the current phenomenon of misuse of high beams is quite serious. Using high beams at the wrong time will not only not improve driving safety, but will increase the probability of dangerous accidents. What are the consequences of incorrect use of high beam lights in real life? How should we use high beam lights correctly?
The effect of high beam lights
There is no doubt that high beam lights can improve the line of sight and expand the field of observation. On a dark road without street lights, the visual range after turning on the high beam is much greater than that of only turning on the low beam. Therefore, in such an environment, it is very necessary to turn on the high beam. From the renderings below we can easily see the advantages of high beam lights.
Hidden dangers caused by high beams
According to Article 48 of my country's Road Traffic Safety Law: high beams should not be turned on when driving on street lights or other well-illuminated roads. Vehicles with high-beam headlights on should switch to low-beam headlights before meeting another car.
Although everyone is well aware of the adverse effects of not switching lights, there are still some people who insist on driving with high beam regardless of the feelings of others. They may think that as long as they can see the oncoming car clearly, there will be no danger. If If you have such thoughts, you are totally wrong. Let's simulate some scenarios to see where the hidden dangers are when turning on the high-beam headlights to meet a car?
◆ When meeting cars head-on:
Hidden danger 1: Instantaneous blinding
When meeting cars at night, high beam lights can blind the oncoming driver visually for an instant. The blinding time depends on the driving time. The driver's own vision and the duration will be different depending on the surrounding environment, but it will last for about seconds at the fastest. During these two seconds, the driver can observe the surrounding pedestrians and the cars coming in front and behind as if driving with his eyes closed. dropped significantly.
Hidden danger two: Reduced perception of speed and distance
Sight at night is not good, so the human eye’s judgment of the speed of oncoming cars will be compromised. In this case, turn on the high beam to Interference from the human eye will accelerate the decline of this judgment. When you turn on the high beam, the oncoming vehicle misjudges your speed and distance. When it should slow down to meet the other car, it calmly avoids the bicycle or starts overtaking. At this time, the high beam can be counterproductive.
Hidden danger three: Decreased judgment of width
Similar to the principle of hidden danger two, the large halo produced by the high beam will occupy a large part of the human eye's vision, thus making the driver's judgment of oncoming traffic difficult. The car's width and judgment of what's behind it diminishes. As a result, incorrect actions may be taken.
◆ The vehicle behind turns on the high beam:
Hidden danger: When the car behind turns on the high beam, a large halo will appear in the rearview mirror of the car in front. If the car that catches up with you is shallow, decoration, the interior of the car will undoubtedly be as bright as if the lights were on. The three halos in front will reduce the visual range of the road ahead of you. If you want to merge or turn at this time, it is completely impossible to observe the situation behind you through the rearview mirror.
It can be seen that using high beam at the wrong time will not only not improve driving safety, but will also increase the risk factor. For those who knowingly commit the crime, this dangerous behavior is tantamount to a kind of "murder". At the end of this article, we have summarized the major "crimes" of incorrect use of high beams, and also given some daily light usage suggestions to all driver friends, so that high beams can truly help us improve driving safety.
Count 1: Using high-beam headlights to meet another car can cause the car to be blinded instantly, which is extremely dangerous.
Count 2: When facing the high beam, the driver has errors in the speed and distance of the oncoming vehicle, and is prone to misoperation.
Count 3: Things behind the high-beam headlights are difficult to detect by the target vehicle.
Suggestion 1: Slow down the speed of the car: visibility is not good at night, and slowing down the speed of the car is always more beneficial to safety than turning on the high beams.
Suggestion 2: Use high beams as little as possible: Nowadays, urban road lighting facilities are relatively abundant, and it is difficult to encounter dark roads at night. Generally, when driving under such road conditions, try not to use high beams.
Recommendation 3: Lights can be used alternately when necessary: When driving on some roads with poor lighting conditions, in order not to affect oncoming cars, high beams can be used alternately with low beams. When there are cars coming from the opposite direction, Should switch immediately.
Suggestion 4: Check your own light status frequently: When you encounter an oncoming car that frequently switches its lights to illuminate you, you should check whether your high beam is turned on inadvertently.
Recommendation 5: Disable high-beam lights in foggy weather, because the air transparency is poor at this time, and the light will have a diffuse reflection effect in the air. Not only will it not allow you to see further, but it will increase the visibility of oncoming cars. Impact.
Suggestion 6: If the vehicle model can adjust the height of the headlights, please adjust it. Due to the high body height of many models, even if the low beam headlights are turned on, it will have some visual impact on oncoming cars similar to the high beam headlights. It is recommended that car owners who often use the car in the city should try to adjust the headlights if they have a headlight adjustment function. Lower the angle to avoid disturbing other vehicles as much as possible.
Suggestion 7: If the other party turns on the high beam, you can also use the high beam switch to remind the other vehicle to turn off the high beam
