Can fog lights be brighter than headlights?

The brightness design standard of fog lamps differs from that of ordinary headlights, with their core lying in penetration rather than absolute brightness. According to technical specifications, the luminous intensity of rear fog lamps should reach more than 50,000 candelas, with the colour temperature controlled at around 6000K, and high-brightness red light sources are used to ensure clear recognition in low-visibility environments. Front fog lamps mostly use 35W yellow light sources, with a colour temperature ranging from 3000-3500K, and utilize the long-wave characteristic to enhance penetration in fog. Although the power of fog lamps is usually lower than that of high-beam headlights (with an upper limit of 55W compared to 45-60W for high-beam headlights), due to their special optical design and concentrated irradiation angle, the effective visibility of fog lamps may exceed the effect of ordinary headlights after being scattered by fog in specific scenarios such as heavy fog. Regulations strictly restrict the abuse of fog lamps; they should only be turned on when visibility is below 200 meters. The correct use of the vehicle lighting system should follow: in foggy weather, prioritize the combined use of front and rear fog lamps with low-beam headlights, strictly prohibit turning on high-beam headlights to cause a screen effect, and at the same time maintain a speed and distance consistent with visibility conditions.
