Car headlights, also known as car headlights, are mainly responsible for the lighting work of driving at night and can be said to be the "eyes" of the car.

Car headlights include high beams and low beams, both of which are used to illuminate the road ahead of the vehicle. The difference is that one is close and the other is farther. 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 is more concentrated, and the bright spot is large, which can be irradiated to higher and farther places (the irradiation distance varies according to the material of the headlights). there will be differences).

●How do you see if you are turning on low beam or high beam?

Many people may think it is incredible, and they don't know whether to turn on the high beams! But in reality, there are indeed some car owners who do not know that they have turned on the high beams during driving.

In fact, it is very simple to see if the high beams are turned on. Although the high beam and low beam logos are similar, they are still very different. As shown in the figure above, the icon on the left with a straight line is the symbol of the high beam, and the icon on the right of the diagonally downward line is the symbol of the low beam. (Some models will not have instrument indication when the low beam is turned on)

●Why do you need to switch the dipped beam when you meet at night?

Because the angle of the high beam is too high, it is easy to shake the glasses of oncoming vehicles and surrounding pedestrians, affecting their vision, thus bringing a great safety hazard to driving. In addition, it is also an impolite driving behavior to turn on the high beams of a car, and it is easy to cause dissatisfaction among other car owners.

The light of the dipped beam is directed downwards. Between 12-18 meters in front of the car, there is a very obvious light-dark cut-off line (as shown in the figure). The ground-reflecting light source can distinguish bright-colored objects in this area, but it is difficult to detect dark-colored objects that are stationary on the road. So be careful when driving at night.

●When do you need to switch the low beam?

In the process of driving, the owner should immediately change the high beam to the low beam if he encounters the following situations:

First, there is a car coming from the opposite side;

Second, the distance from the vehicle in the same direction in front is relatively close;

The third is when there is enough illumination on the road;

Fourth, when entering a street with heavy traffic.

●How to switch between low beam and high beam?

The switch for the high and low beam lights of a car is usually on the left side of the steering wheel. When the switch is turned to the low beam position, the high beam and low beam lights will flash when the lever is turned inward, and the high beam lights will always be turned on when the switch is turned outward. (some special models will be slightly different)
