Why is the car's position light not working?

[BryceRose]

If only one position light is not working, it is likely a bulb issue. If one side or all position lights are not working, it may be due to a fuse or switch problem. Below is an introduction to the functions of position lights: 1. Driving in fog: Due to reduced visibility, turning on the position lights along with the fog lights provides a good warning to other road users. 2. Rainy weather: Position lights serve as a warning to both preceding and following vehicles, helping to avoid accidents. 3. Night driving: It is mandatory to turn on the position lights and rear tail lights at night as per traffic regulations to alert following vehicles. 4. Dusk: When street lights are absent and vehicle lights are not very bright, turning on the position lights ensures other vehicles can see your car for safety.
