What is the difference between high beam and low beam?

[AdamAnn]

The difference between high beam and low beam lies in their icons: the high beam icon has lines pointing straight forward, while the low beam icon has lines pointing downward. The usage scenarios for high and low beams include: 1. When overtaking, the driver should turn on the left turn signal in advance and switch between high and low beams or honk to alert the vehicle ahead to yield; 2. When unfamiliar with the road and needing to read road signs or other indicators, the high beam can be used but should be quickly switched back to low beam; 3. When driving at night with no streetlights, poor lighting, or in low visibility conditions such as fog, rain, snow, dust, or hail, the headlights, position lights, and taillights should be turned on. However, the high beam must not be used when a vehicle is closely following another vehicle in the same direction.
