What is the difference between front fog lights and low beam headlights?

[DeElizabeth]

The differences between front fog lights and low beam headlights are: 1. Different usage environments: (1) Fog lights: Must be used in weather conditions with visibility below 200 meters. (2) Low beam headlights: Must be turned on when driving in areas without streetlights at night, during dusk when it's dark, or at dawn; if encountering heavy fog, snow, or heavy rain that obstructs visibility, they must also be turned on even during the day; in some areas where lighting is insufficient, low beam headlights should also be used. 2. Different functions: (1) Fog lights: Serve to warn and penetrate through fog. (2) Low beam headlights: Provide close-range illumination. 3. Different characteristics: (1) Fog lights: Have higher luminous intensity than taillights, with high brightness and strong penetration, avoiding diffuse reflection caused by fog. (2) Low beam headlights: Have a wide illumination range (160°), short illumination distance, non-adjustable focus, and a very distinct cutoff line between light and dark.
