Reasonable use of lights while driving is very important to improve driving safety; there are still many doorways for the use of lights. Many car owners only know about low beams and high beams, but don"t know much about fog lights. They always confuse them. Inappropriate use not only affects the safety of others, but is also detrimental to oneself, so how to use and maintain automobile fog lights, let"s understand together!

What is a car fog lamp

Automotive fog lights are generally installed on the front and rear of the car to illuminate the road and provide safety warnings when driving in rainy and foggy weather. The visibility between the driver and the surrounding traffic participants is improved, making it easier for the surrounding traffic participants to find each other.

Front fog lights

The front fog lamp is set on the front bumper, and the position is slightly lower than the headlamp. The front fog lamp is generally yellow. Because of the strong light penetrating power of yellow, it can improve the visibility of the driver and the surrounding traffic participants, so that the oncoming traffic And pedestrians found each other far away.

Front fog lamp graphic style: three diagonal lines on the left, which are crossed by a curved line, and a semi-ellipse on the right.

Rear fog lamps

Rear fog light refers to a red signal light that is installed at the rear of the vehicle to make it easier for other road traffic participants behind the vehicle to find it in an environment with low visibility such as fog, snow, rain or dust. The luminous intensity is greater than that of the tail light.

There is a little difference between the rear fog lamp sign and the front fog lamp. The light line of the front fog lamp sign is downward, and the rear fog lamp is parallel, which is generally located on the dashboard of the car. Rear fog lamp graphic style: the left side is a semi-elliptical graphic, and the right side is three horizontal lines, which are crossed by a curved line.

Fog lamp switch design

Because the fog lamp switch is generally divided into three gears, the 0 position is closed, the first gear controls the front fog lights, and the second gear controls the rear fog lights. The front fog lights work when the first gear is turned on, and the front and rear fog lights work together when the second gear is turned on.

When to use car fog lights

In severe weather conditions such as fog, snow and heavy rain, or driving in a smoky environment, in order to illuminate the road ahead and ensure driving safety, front fog lights must be used. In foggy weather, the front and rear fog lights are usually used together. Do not use fog lights when driving without fog at night in the city. The front fog lights have no hood, which will make the car 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 power of the rear fog lights is relatively high, it will cause dazzling light to the car drivers behind, which may cause eye fatigue and affect driving safety.

Fog lamp replacement and maintenance

Whether it is the front fog lamp or the rear fog lamp, as long as it does not light up, it means that the bulb has burned out and must be replaced. However, if it is not completely broken, it is just that the brightness is reduced, and the lights are red and dim, and you must not take it lightly, because this may be a precursor to a failure, and the reduced lighting capacity is also a major hidden danger to safe driving.

The reason for the low brightness of fog lights

1. The most common thing is that there is dirt on the astigmatism glass or reflector of the lamp. At this time, all you need to do is to remove the dirt with a flannel or lens paper.

2. Another reason is that the charging capacity of the battery is reduced, and the brightness is not enough due to insufficient power. In this case, a new battery needs to be replaced.

3. There is another possibility that the wire is aging or the wire is too thin, which causes the resistance to increase and affects the power supply. This situation not only affects the operation of the bulb, but can even cause the circuit to overheat and cause a fire.

The usual maintenance is done well, which can play a great role in safe driving.

Knowledge of fog lights not only guarantees their own safety, but also protects other traffic participants.
