What's the difference between fog lights and low beam lights? Are the fog lights and low beam lights on together?

Fog lamps and low beam lamps are different in lighting angle, brightness and light source penetration.

In these respects, fog lights are also better than low beam lights.

The function of the low beam lamp is to illuminate a certain range in front of the car, the irradiation angle is also lower than the horizontal line, and the power of the bulb is not too large, which will not interfere with other drivers!

But in the fog, the low beam with weak penetration is also difficult. At this time, it is also necessary to rely on fog lamps to make up for the shortcomings that low beam lamps cannot penetrate heavy rain and dense fog. Therefore, fog lamps can only be used as emergency lighting tools under bad weather conditions, not as ordinary lighting!
