What is the difference between fog lights and high beams?

[DelBeau]

The differences between fog lights and high beams mainly lie in their purpose, brightness, light penetration, and illumination distance. The specific differences are as follows: High beams have a higher angle and longer distance, with more concentrated light, suitable for extremely poor lighting conditions where they do not affect other road users. Fog lights can only be used in poor visibility weather conditions. Fog lights have a good scattering light source, providing strong penetration in fog, rain, or snow, alerting oncoming drivers to safety. The usage of high beams is as follows: 1. High beams should not be used when driving at night with streetlights. 2. High beams can be used when there are no streetlights and very few vehicles on the road. 3. When using high beams, switch to low beams when encountering oncoming traffic. 4. If the other vehicle uses high beams during nighttime encounters, flash the high beams 1-2 times to remind them to switch to low beams.
