As the name suggests, fog lights are lights that are turned on in foggy days, which can effectively prevent traffic safety accidents. So under what circumstances are fog lights used? Let’s take a look at the situations where fog lights need to be used.
Under what circumstances are fog lights used?
As I said above, fog lights are lights used in heavy fog and other weather with low visibility. According to the Road Traffic Law, when visibility is less than 200 meters in rainy and foggy days, motor vehicles should turn on their fog lights.
Of course, this 200 meters is only a safe driving distance. Whether to turn on the fog lights immediately depends more on the actual situation. In addition, many car owners think that it does not matter whether they turn on the fog lights or not because the speed is not too fast in urban areas. In fact, this idea is wrong. In daily driving, fog lights should be turned on whenever one of the following conditions applies:
When the smog covers
Needless to say, it is necessary to turn on the fog lights in heavy fog, so as not to hit others and to avoid being hit by others.
However, it should be noted that although fog lights can help vehicles or pedestrians see them early, it does not mean that they can be used at all times, especially when the front and rear fog lights are turned on. Because fog lights are brighter than ordinary car lights and have strong scattering, if they are lit randomly when unnecessary, they will only interfere with the sight of other motorists, especially the sight of oncoming cars. In serious cases, it may Causing a car accident. Therefore, traffic regulations in many countries clearly stipulate that vehicles are prohibited from turning on fog lights when visibility is good.
Under what circumstances are fog lights used?
when it pours
When heavy rain pours down, a driver's vision is easily blurred, and sometimes it is difficult to judge the surrounding situation. At this time, you can consider turning on your fog lights to alert drivers around you of your presence.
How to maintain fog lights
When driving without fog in the city at night, do not use fog lights. The front fog lights do not have sunshades, which will make the vehicle lights dazzling and affect driving safety. Some drivers not only use the front fog lights, but also turn on the rear fog lights. Because the rear fog light bulb has a large power, it will produce dazzling light for the car driver behind, which can easily cause eye fatigue and affect driving safety.
Whether it is a front fog light or a rear fog light, as long as it does not light up, it means that the bulb has burned out and must be replaced. But if it is not completely broken, but the brightness is reduced and the light is red and dim, you must not take it lightly, because this may be a precursor to failure, and the reduced lighting capability is also a major hidden danger for safe driving.
There are several reasons for the decrease in brightness. The most common one is the accumulation of dirt on the diffused glass or reflector of the lamp. All that needs to be done at this time is to clean the dirt with a flannel or lens paper. Another reason is that the battery's charging capacity decreases and the power is insufficient, resulting in insufficient brightness. In this case, the battery needs to be replaced with a new one. Another possibility is that the circuit is aging or the wire is too thin, causing the resistance to increase and affecting the power supply. This situation not only affects the work of the light bulb, but may even cause the circuit to overheat and cause a fire.
The above introduces the relevant content under what circumstances fog lights are used. Let’s take a look at the functions of common car lights.
1. The function of the door indicator light:
Used to display the status of each door of the vehicle. If any door is not closed or not closed properly, the indicator light will light up the corresponding door indicator light to remind the owner that the door is not closed properly. When the door is closed or closed properly, the corresponding door indicator light will go out. .
2. The function of the oil level indicator light:
It is used to display the amount of fuel stored in the vehicle. When the key door is opened and the vehicle performs self-check, the fuel level indicator light will light up for a short time and then go out. If the indicator light comes on after starting, it means there is insufficient fuel in the car.
3. The function of the ABS indicator light:
Used to display ABS working status. When the key door is opened and the vehicle self-checks, the ABS light will come on for a few seconds and then go off. If it does not flash or does not go out after starting, it indicates that the ABS is faulty.
4. The function of the handbrake indicator light:
Used to display the status of the vehicle's handbrake, which is usually off. When the handbrake is pulled up, the indicator light automatically lights up. When the handbrake is released, the indicator light automatically goes out. Some models will be accompanied by a warning sound if the handbrake is not released while driving.
5. The function of the brake disc indicator light:
Used to show the wear status of the vehicle's brake disc. Generally, this indicator light is off. When the brake disc fails or is excessively worn, the light will light up and will go out after repair.
6. The function of the seat belt indicator light:
It is used to show whether the seat belt is in a locked state. When the light is on, it means that the seat belt is not fastened in time. Some models will have corresponding prompts. When the seat belt is fastened in time, the indicator light automatically goes out.
7. The function of the oil indicator light:
Used to display the oil pressure in the engine. When the key door is opened and the vehicle starts self-checking, the indicator light comes on and goes off after starting. This indicator light is always on, indicating that the engine oil pressure of the vehicle is lower than the specified standard and requires maintenance.
8. The function of the water temperature indicator light:
It is used to display the temperature of the coolant in the engine. When the key door is opened and the vehicle self-checks, it will light up for a few seconds and then go out. If the water temperature indicator light is always on, it means that the coolant temperature exceeds the specified value and the vehicle needs to be stopped immediately. It goes out when the water temperature becomes normal.
9. The function of the air bag indicator light:
It is used to display the working status of the airbag. When the key door is opened and the vehicle starts self-checking, the indicator light will automatically light up for a few seconds and then go out. If it stays on, the airbag is malfunctioning.
10. The function of the battery indicator light:
Used to display battery usage status. This indicator light comes on when the key door is opened and the vehicle starts self-test. Automatically extinguishes after starting. If the battery indicator light stays on after starting, it means there is a problem with the battery and needs to be replaced.
The above is all the sharing about the circumstances under which fog lights are used and the situations where fog lights need to be used. I hope it will be helpful to everyone.
