Before turning on the fog lights, you need to turn on the parking lights. Fog lights: Generally refers to automotive fog lights, which are installed on the front and rear of the vehicle. They are used for road illumination and safety warnings during rainy or foggy weather, improving visibility for the driver and other road users. Function: Their purpose is to make the vehicle visible to others in conditions of reduced visibility, such as fog or heavy rain. Therefore, fog light sources need to have strong penetration. Most vehicles use halogen fog lights, while LED fog lights are a more advanced option. Fog lights must be installed below the bumper, at the lowest point of the vehicle body, to ensure their effectiveness. If installed too high, the light cannot penetrate the rain or fog to illuminate the road, which can easily lead to dangerous situations.
When I first started driving, I tried turning on the fog lights on a rainy day, but nothing happened no matter how long I pressed the button. Later, a veteran driving instructor told me that before using the fog lights, you must first turn on the headlights (the main front lights of the car). This is because fog lights are auxiliary lighting, and their circuit design relies on the power supply system of the headlights. If you don't turn on the headlights first, the fog light switch might not work, acting like a small safety feature of the car. Fog lights are mainly used in heavy fog or heavy rain to help illuminate the low area in front of the car, but avoid using them in normal weather as it can affect other drivers' visibility. Remember to check the lighting system every time you get in the car; developing this habit can help avoid unnecessary trouble.
