When Should Fog Lights Be Used?

[MacAlex]

Fog lights are used in conditions where visibility is significantly affected by weather, such as foggy or rainy days. They are installed at the front and rear of the vehicle to illuminate the road and provide safety warnings during inclement weather. Fog lights are divided into front fog lights and rear fog lights. Front fog lights are typically bright yellow, while rear fog lights are red. The symbols for rear fog lights differ slightly from those of front fog lights: the front fog light symbol has downward-pointing light lines, whereas the rear fog light symbol has parallel lines, located on the dashboard inside the vehicle. Uses of fog lights: 1. The primary function of fog lights is to make the vehicle visible to others in conditions of poor visibility due to fog or rain. Therefore, the light source of fog lights needs to have strong penetration. 2. 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 fog or rain to illuminate the road, which can lead to hazards. 3. The fog light switch generally has three positions: position 0 is off, position 1 controls the front fog lights, and position 2 controls the rear fog lights.
