What light should I turn on when driving in foggy night?

Fog lights, hazard warning flashlights and headlights

When driving in foggy weather, turn on fog lights, danger warning flashlights and headlights in time. Fog lamps generally refer to automobile fog lamps. Automobile fog lamps are installed at the front and rear of the automobile, which are used to illuminate the road and give safety warnings when driving in rainy and foggy weather. The visibility of drivers and surrounding traffic participants is improved. Danger warning flashes, often called "double jump" (there is one in the red triangle! Sign button switch (commonly known as double flashing light or double jumping light) is a kind of signal light to remind other vehicles and pedestrians to pay attention to the special situation of this vehicle.

Car headlights includes light source, reflective bowl, lamp shell, power supply circuit, etc. Generally, only the light source is replaced, and the light source itself is consumables. The life of traditional halogen lamps is only about 600 hours, and the brightness will decrease after the life, which will affect the driving safety. The annual inspection has minimum brightness requirements for lights.

To restore the brightness of the lights from the factory, it is only necessary to replace a light source with the same model and specifications as the original car. Replacing the light source is not particularly professional. Most cars with halogen headlights have bulb replacement interfaces, so you don't need any tools. You just need to open the dust cover of the headlight, unplug the power cord, put on a new light bulb, and then restore it. There are many detailed videos on the Internet.

To upgrade headlights legally, it is necessary to choose the interface and light emitting position as close as possible to the light source of the original car.

In order to illuminate the road ahead and ensure driving safety, cars must use front fog lights when driving in bad weather conditions such as fog, snow and heavy rain, or in a smoky environment. In recent years, fog lamps are mostly installed on the front bumper in styling design. There are many similar lights, such as high beam and low beam, as well as front fog lights and rear fog lights.

After turning on the width light, you can turn on the fog light. It is worth mentioning that the front fog lights are controlled separately, and the rear fog lights must be turned on at the same time as the front fog lights, and cannot be turned on separately. There are several kinds of automobile fog lamp switches, namely knob type and key type, among which knob type is the most common.

Turning on the knob is very simple. Just turn the switch to the corresponding position and you can choose to turn on the front and rear fog lights. Needless to say, the key type can realize the corresponding function by pressing it directly.
