What is the difference between high and low beams?

The high beams can radiate farther away, allowing the driver to better see the traffic in the distance. It plays an important role in traffic safety.

The low beam is for close lighting, and the design requirements are to have a large irradiation range (160°), a short irradiation distance, and the light concentration cannot be adjusted.

High beams and low beams are lights that we must learn to use, cars need to have these two lights, not only one kind of light, there is no better way to say which light, in case of different situations, you need to use high and low beams according to the regulations. Many people don't know what lights should be turned on on the highway, so let's analyze what lights to use on the highway.

The answer in many people's minds may be low beams, and everyone's driving habits may not be the same, but the standard operation is that running at high speed at night and turning on the high beams is the correct operation and safer, why?

First of all, there are generally no street lights on the highway, and most of the highways are in the suburbs, and it is dark everywhere at night, and the low beam lights are not enough in terms of brightness or irradiation distance; The high beam has the advantages of high brightness and long irradiation distance, which is more suitable for high-speed driving at night.

Secondly, the speed of the high-speed is relatively fast, the low beam irradiation distance is limited, if there are obstacles or other abnormal situations in front of it, it is difficult to find it in advance, and when it is found, it is very close, it is too late to dodge, it is very dangerous, so we have to use high beams at this time.

Some people may say, aren't you afraid of affecting other people's driving vision when you turn on your high beams?

In fact, there is no need to worry too much about this, first of all, there are bushes in the middle of the expressway, which basically does not affect the line of sight of the oncoming lane; Secondly, on the highway, because the speed of the car is fast, the distance between the car is also relatively large, generally more than 100 meters or even more than 150 meters, even if the high beam is turned on, the impact on the front car rearview mirror and endoscope is relatively small, so do not worry too much about affecting the line of sight of the car in front. If you are close to the car in front, you should switch to the low beams and wait until you have re-distanced yourself before switching to the high beams.

The role of these two lights is not the same, and the effect is best with the right light in the right situation.

High beams and low beams have their own benefits, there is no comparison, in the field where the light is darker, it is best to use high beams, while in urban areas, high beams can not be used, only low beams.

Both high and low beams have their own benefits and are suitable for different environments. For example, high beams are usually suitable for open roads with no street lights, while low beams are usually suitable for situations such as the intersection of two vehicles and close following.

When driving on the highway at night, do you turn on the high beams or low beams? Whether it is for old drivers or novice drivers, the three words "Yuanguang Dog" can be described as "deeply rooted in the hearts of the people"! Many new and old drivers have this question - do you use high beams or ruler low beams when driving at high speed at night?

Xiao Wan is here to tell you that if you are driving at high speed at night, it is best to turn on the high beams. First of all, most of the high-speed sections have isolation belts, and the use of high beams in general family cars and SUVs will not affect the oncoming cars on the opposite side, so you can use them with confidence. Secondly, most of the high-speed sections do not have street lights, if you use low beams, the lighting situation will be poor, in the case of fast speed, what conditions on the road may not have time to react, easy to cause accidents.

Of course, if you pass through a highway section without a separation zone, when there is an oncoming car on the opposite side, you still have to switch to low beam to avoid obstructing the view of the oncoming traffic. After the interaction between the cars, switch to the high beams and continue driving. If the other party's high beam gets in the way, you can switch the high and low beam three times in a row to remind the other party that if the other party cuts the low beam, you can also cut the low beam, and if the other party does not react, you can also continue to use the high beam, there is no need to be humble in this situation.

Apart from the highway, what sections of the road are it necessary to use high beams?

If the road lighting is not good in the non-high-speed section, you can use the high beam first, and the opposite car will switch in time to ensure safety.

In addition, we should also remind everyone to pay attention to one point, do not use headlights because the road lighting is enough, the headlights of the vehicle have two functions, the first is to let others see you, and the second is to illuminate the road in front of you, especially in the tunnel, it is recommended to turn on the headlights, so as not to cause accidents when other vehicles can not see your car when changing lanes. Rational use of lights, scientific use of lights, and standardized use of lights, so as to ensure the safety of car travel, I hope to help new and old drivers.

They are all used to shine at night, but the high beam angle is high and the distance is long, and the low beam angle is low and the distance is close.

Generally, it is best not to drive high beams when driving in the city, because the lighting conditions in the city are generally better. If the angle of the high beam is too high, it is easy to shake the glasses of oncoming cars and surrounding pedestrians, affecting their vision, which is very unsafe and is an impolite driving behavior.

However, at night, the high beam can be turned on and off alternately to warn pedestrians and vehicles around the horn to avoid causing too much noise.

When driving in places with high car wheel speed and no street lights in the suburbs, you can turn on the high beam to expand the field of vision. However, when there is a car on the opposite side and you need to meet the car, for the sake of safety and politeness, switch this sail into a low light.

Hello, there must be a difference between low beam and high beam, literally, low beam must be illuminated a little closer to the normal driving of the sedan chair is recommended to use the key sail to do low beam, the high beam of the draft balance must be a little farther, on the high speed, you can choose to use the high beam is safer.

There is a difference between high beams and low beams, high beams illuminate relatively long distances, and high beams can be used for running high speed at night.

Hello, high beam and low beam, he is just an angle difference, the angle of high beam is relatively high.

Hello, the angle of the high beam will be higher, and the irradiation distance will be a little farther. The low beam is lower.

1.Different light intensity: the light emitted by the low beam light is outside the focal point, and the light emitted is in a divergent state, which can illuminate a large range of objects in the near distance; The high beam is on the focal point, and the light emitted will shoot out in parallel, and the brightness is large, and it can illuminate very high objects.

2.Different irradiation distances: low beam lights are for close lighting, the irradiation distance is short, and the concentrator cannot be adjusted; High beams are used for long-distance illumination, long distance, and high brightness.

3.The use of the low-beam is different: the low beam is used when driving on the city road, because the general lighting conditions in the city are better, if the high beam is turned on, it is very easy to shake the vehicle driving in the opposite direction and cause an accident; The high beam can be turned on when driving at high speeds and in places where there are no street lights in the suburbs, expanding the field of vision.

Both high beams and low beams are used to illuminate the road ahead of the vehicle. Under normal circumstances, the irradiation distance of the low beam is about 30-40 meters, and the irradiation range is about 160 °, while the high beam light is more concentrated, the bright spot is large, and it can be irradiated to higher and farther places, of course, the irradiation distance will be different according to the different headlight materials. Since both low beam and high beam are headlights, the lighting effect of headlamps directly affects the operation and traffic safety of night driving.

You should turn on your low beams when driving in dark areas where there are no street lights and when it is dark in the evening or when the dawn is just beginning to appear. Of course, there are also some sections of the road that have lighting, but the brightness is not enough, so you should also turn on the low beams.

The high beam is at its focus, and the light emitted will shoot out in parallel, the light is more concentrated, the brightness is larger, and it can illuminate very distant and high objects; The low beam light emits outside its focal point (between 1x and 2x the focal point) and the light emits in a divergent state, which can illuminate a large area of objects in the vicinity. Low beam lamps are used for close illumination (about 30 40 meters), and the design requires a large irradiation range, a short distance, and the concentration cannot be adjusted; High beams are used to illuminate at long distances, with long distances and high brightness.

The sign for the low beam is green. The sign of the low beam is that the light is shining on the left, diagonally downward. On the dashboard, the low beam is green.

The logos for high beams and low beams are similar, but they are also very different; The icon with a straight line on the left is the sign of the high beam, and the icon with a slash line on the left is the sign of the low beam.

If you turn on the low beam, you may not find the low beam icon on the dashboard, this is because the low beam indicator is not necessary, so many manufacturers have omitted it, but turn on the high beam, you will find that the blue high beam icon on the dashboard lights up immediately.

The low beam must be turned on in the following situations:Turn on your low beams when driving in dark areas where there are no street lights and when it is dark in the evening or when dawn is at dawn. If you are caught up in fog, snow or heavy rain and your vision is clouded, then you must turn on your low beams even during the day; In some sections, although there is lighting, but the brightness is not enough, you should also turn on the low beams.

The low beam is a short-distance illumination, and the design requirements are a large irradiation range (160°), a short irradiation distance, and the concentration is not adjustable.

At its focal point, the high beam emits light in parallel, the light is concentrated and bright, and it can shine on very high objects.

The difference between high beams and low beams is that both are used for night lighting, but the high beams have a long angle and the low beams have a close angle.

How do you see if you're on low beam or high beam?

Many people may find it incredible. I don't know if the high beams will turn on! But in reality, there are also some car owners who don't know that they have turned on their high beams when driving.

In fact, it's easy to see if the high beams are on or not. The logos for high and low beams, while similar, are very different. As you can see in the image above, the straight line on the left is the sign of the high beams, and the icon of the downward diagonal line on the right is the sign of the low beams (some models do not have a gauge indication when the low beams are on).

Use the high beams correctly.

Slow down: Poor vision at night. Slowing down is always more helpful for safety than turning on the high beams.

Use high beams as little as possible: Nowadays, urban roads are more abundantly lit, and it is difficult to encounter dark roads at night. In general, you should try not to use your high beams when driving in such road conditions.

When necessary, the lights can be used alternately: when driving on some roads with poor lighting conditions, in order not to affect oncoming vehicles, high beams can be used alternately with low beams, and when there is oncoming traffic, they should be switched immediately.

Always check the status of your lights: When you encounter oncoming cars and frequently turn on and off your lights to illuminate yourself, check whether your high beams are turned on unintentionally.

High beams are forbidden on foggy days, because the transparency of the air is poor, and the light will spread in the air of the air, which will not only allow you to stare farther away, but also increase the impact on the oncoming car.

SUV, if you can adjust the headlight height, adjust it. Many SUVs are taller, and even with low beams on, they will have some visual effects similar to high beams. It is recommended that car owners who often use it in the city, if there is a headlight adjustment function, try to reduce the headlight angle and try to avoid interfering with other vehicles.

If the other party turns on the high beams, you can also use the high and low beam switching to remind the other party's vehicle to turn off the high beams.
