What is the difference between front fog lights and low beams?

Difference between fog lights and low beams: In terms of beam angle, brightness, and light penetration, fog lights are superior to low beams. Fog lights generally refer to automotive fog lights. Automotive fog lights are installed at the front and rear of the vehicle to illuminate the road and provide safety warnings during rainy or foggy weather, enhancing visibility for the driver and other traffic participants. Low beams are designed for short-distance illumination, with a wide coverage range (160°) but a short projection distance, and the focus cannot be adjusted. The projection distance of low beams is approximately 30-40 meters. Function and usage time of fog lights: Fog lights have strong penetration. In heavy fog, they can cut through dense fog, allowing drivers to see the road ahead clearly. However, fog lights should only be used in heavy fog conditions. Their power is much higher than that of low beams, and their beam angle, brightness, and penetration are also significantly higher. While they are highly effective in heavy fog, their intense penetration can be glaring. Using fog lights in normal weather conditions can cause significant interference for drivers of vehicles ahead or behind, easily leading to accidents. When to use low beams: When encountering other vehicles or pedestrians, switch to low beams. When unfamiliar with the road and needing to read road signs or other markers, high beams can be used but should be quickly switched back to low beams. When overtaking another vehicle, the left turn signal should be activated in advance, and high beams or the horn should be used to alert the vehicle ahead to yield. When driving in dimly lit areas without streetlights, low beams must be turned on. How to turn on fog lights: Press the front and rear fog light buttons on the car to activate them. How to turn on low beams: On the left side of the steering wheel, there is a set of light combination switches. At night, rotating the combination switch forward one notch turns on the dashboard lights, and rotating another notch turns on the low beams.
I used to wonder what the difference was between front fog lights and low beams. Simply put, low beams are standard nighttime driving lights that shine downward to illuminate the road ahead without blinding oncoming drivers. Front fog lights, on the other hand, are designed specifically for bad weather. Mounted lower on the front of the car, they emit a wide-angle, diffused light that can penetrate fog, heavy rain, or snow, reducing glare from reflections. When I drive on highways, I often encounter fog, and without fog lights, visibility is poor, making accidents more likely. But remember, fog lights aren't for everyday use—they should only be turned on when visibility drops below 50 meters. Using them in clear weather can distract other drivers and is even illegal. Regularly checking if the lights are working is crucial. I clean the lamp covers every three months to prevent dust buildup from affecting performance. Safe driving involves paying attention to these small details, which can make nighttime driving much more reassuring.
