Anti-fog lights are divided into front fog lights and rear fog lights. The front fog lights are generally bright yellow, and the rear fog lights are red. There is a little difference between the rear fog light logo and the front fog light. The light line of the front fog light logo is downward, and the rear fog light is parallel, and is generally located on the dashboard of the car. Because the anti-fog lamp has high brightness and strong penetrability, it will not produce diffuse reflection due to fog, so the correct use can effectively prevent accidents. In foggy weather, the front and rear fog lights are usually used together.
Red and yellow are the most penetrating colors, but red represents "no traffic", so yellow is chosen. Yellow is the purest color. The yellow anti-fog lamp of a car can penetrate thick fog and shoot far away. Because of the backscatter, the driver of the vehicle behind turns on the headlights, which increases the background intensity and makes the image of the vehicle in front more blurred.

use
The function of the fog lamp is to allow other vehicles to see the vehicle when the visibility is greatly affected by the weather in fog or rain. Therefore, the light source of the fog lamp needs to have strong penetrability. Common vehicles use halogen fog lights, and LED fog lights are more advanced than halogen fog lights.
The fog lamp can only be installed below the bumper, where the car body is closest to the ground, to ensure the function of the fog lamp. If the installation position is high, the light cannot penetrate the rain and fog to illuminate the ground (fog is generally below 1 meter) Relatively thin), easy to cause danger.
Since 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. Therefore, when turning on the fog lights, it is recommended to know which gear the switch is in, so as to facilitate yourself without affecting others and ensure driving safety.
