What are the headlights of the car? High beam or low beam.
Headlights usually mean high beam.

High beam and low beam are opposite, commonly known as "headlights". It aims to improve the driver's sight distance by directly illuminating the light with higher brightness than the low beam lamp (the low beam lamp of some models uses the same bulb, and the low beam lamp is blocked by the lampshade) in front of the vehicle.

The function of high beam and low beam is to illuminate the road in front of the vehicle. Generally speaking, the low beam can only cover the distance of 50 meters in front of the vehicle at most, and the high beam can reach hundreds of meters or even more.

Function of high beam

High beam is used to make the line of sight farther, or to increase the visual clarity. Therefore, under normal circumstances, the high beam will be turned on for a long time in the road section without street lights or poor lighting conditions. The high beam is directly in front and has higher brightness, which also determines that it will directly affect the driver in front (glare caused by rearview mirror reflection) and the oncoming car (direct light).

Its direct impact is to greatly narrow the opponent's line of sight. After the high beam disappears for a long time, the eyes will also be "blind". Another function of the high beam is to warn the cars in front and the oncoming cars. Under this function, you usually only need to flash once or twice.
