The function of the fog lamp frame at the front of a car
The main function of the front fog lamp frame of a car is to provide high-penetrating lighting in rainy and foggy weather, helping drivers clearly identify the road ahead and warning oncoming vehicles at the same time. Fog lights are usually installed at a slightly lower position at the front of the vehicle, using yellow or white light sources. They are tilted downward at 30° to 45° to illuminate road markings and obstacles within a 10-meter radius. Youdaoplaceholder0.
Specific functions
Youdaoplaceholder0 Enhance visibility : The light from fog lights can effectively penetrate rain and fog, reducing reflections and glare. When visibility is below 200 meters, turning them on can increase visibility for oneself and surrounding traffic participants.
Youdaoplaceholder0 Warning function : The yellow light from the front fog lights has 40% stronger penetration than that of ordinary headlights. It can be recognized by other vehicles from 300 meters away, avoiding rear-end collisions.
Youdaoplaceholder0 Special scenarios applicable : Besides foggy days, it can also be used in rainy, snowy, sand-dust or night fog conditions to avoid blurred vision caused by light scattering.
Precautions for Use
Fog lights should be turned on when visibility is less than 200 meters to avoid interfering with oncoming vehicles.
The state stipulates that motor vehicles must be equipped with fog lights that meet the standards. Vehicles without fog lights installed are not allowed to enter expressways.
When disassembling the front fog lamp frame of a car, the corresponding tools and operation methods should be selected according to the fixation method:
Screw-fixed type
Prepare the tools: screwdriver, wrench
Locate the screw position (usually on the inside, below or at the edge of the fog lamp frame)
Use the adapter screwdriver to loosen the screw counterclockwise
Snap-on fixed type
Prepare the tools: plastic crowbar or flat-head screwdriver
Insert the tool from the edge of the fog lamp frame and pry the clasp evenly
Combined fixed type
Loosen the screws first
Then pry the clasp
Youdaoplaceholder0 precautions
Avoid operating in high-temperature environments to prevent plastic components from becoming brittle
When using tools, apply gentle force to prevent the clips from breaking or the screws from slipping
When disassembling, be careful to protect adjacent components and wiring connections
Faults in the front fog lamp frame of a car may involve issues with the lamp cover, sealing performance or circuit. Common causes and handling methods are as follows:

Youdaoplaceholder0 Circuit issues : Oxidation, short circuit or open circuit of the circuit need to be investigated, with a focus on checking the sealing of the plug (to prevent mud and water from entering).
Failure of other components
Poor contact of switch : manifested as normal hazard lights but fog lights not lighting up. It is necessary to check the control switch contacts.
Youdaoplaceholder0 relay fault : Poor contact can cause intermittent power outages. You can try replacing it with a relay of the same model for testing.
