When the vehicle is driven at night, the light is the 'eyes' of the vehicle. Automotive high beams are equipped for use in conditions of extremely poor lighting. However, many drivers turn on the high beam as soon as they get on the road and do not change the low beam when they meet, which may cause visual obstruction to other drivers, and may affect normal driving of the vehicle if they are light, or may cause traffic accidents if they are heavy. Improper use of the high beam light can cause instantaneous blindness to the meeting drivers, and the perceptibility to the speed and distance of the vehicle and the judgment of the width can be reduced. Statistics from traffic police departments indicate that of the night driving accidents, about six accidents are related to abuse of high beam.
