The function of fog lamp is to let other vehicles see the vehicle when the visibility is greatly affected by the weather in foggy or rainy days, so the light source of fog lamp needs to have strong penetration.

The role of fog lights:

The function of fog lamps is to enhance lighting in rainy and foggy days. Bulbs are mostly yellow and white. Because of the poor penetration of white light, white light is often required to be about 25% brighter than yellow light.

The light of the fog lamp is restrained by the reflective cup in the lampshade, and shines obliquely below the front of the vehicle to ensure that the driver can see the road ahead at close range and be seen by the opposite vehicle.

Therefore, it should be noted that the installation position of fog lamps can only be below the bumper, and the car body is closest to the ground, so as to ensure the function of fog lamps. If the installation position is high, the light can not penetrate the rain and fog to illuminate the ground at all, which is easy to cause danger.

When the visibility is greatly affected by the weather in foggy or rainy days, other vehicles can see the vehicle, so the light source of fog lamps needs strong penetration. General vehicles use halogen fog lamps, and xenon fog lamps are more advanced than halogen fog lamps.
