Because anti-fog lights have high brightness and strong penetration, they will not cause diffuse reflection due to fog, so correct use can effectively prevent accidents. In foggy weather, front and rear fog lights are usually used together.
How to turn on the fog lights?
Most fog lights are basically on the lever under the steering wheel. As long as there is a fog light icon on the lever no matter what model it is, the rear fog light icon has a straight line in front of the light icon, and the front fog light icon has a light icon. A wavy curve in front.
Of course, you must turn on the small lights before turning on the fog lights. If the small lights are turned off, the fog lights cannot be turned on. The fog light icon lights up to indicate that the fog lights are on. In the on state, the fog light icon will also be displayed on the car dashboard.
What's the difference between front and rear fog lights?
The front fog lamp is a high-brightness diffused light source. The intensity of this light source is to penetrate dense fog and alert drivers in the opposite direction.
The rear fog lamp is a high-brightness red light source. Red is the longest wavelength of visible light. The longer the wavelength, the better the penetration. Its function is to make it easier for drivers behind the vehicle to spot your car in low-visibility environments such as fog, haze, snow, rain or dust.
Front fog lights are generally bright yellow, and rear fog lights are red. The logo of the rear fog light is slightly different from that of the front fog light. The light line of the front fog light logo is downward, while the rear fog light is parallel. It is usually located on the instrument console in the car.
