Different brands and models have different functions.
1. Some are integrated fog lamps, and the fog lamp cover is only for decoration.
2. Some brands of fog lamps are connected with vehicle components by fog lamp cover. There is a slotted fog lamp cover behind the fog lamp cover to cover up.
The fog lamp is installed in the front of the car, slightly lower than the headlamp, and is used to illuminate the road when driving in rainy and foggy weather. Due to low visibility in foggy days, the driver's line of sight is limited. The light can increase the running distance, especially the light penetration of the Yellow anti fog lamp, which can improve the visibility between the driver and the surrounding traffic participants, so that the incoming vehicles and pedestrians can find each other at a distance.
