What are the standard parameters for car headlight adjustment

The two-lamp system should be no less than 15,000cd, and the four-lamp system should be no less than 12,000cd. The high beam intensity of a new car should be no less than 18,000cd for the two-lamp system, and no less than 15,000cd for the four-lamp system. According to the standards stipulated by the state, it is required to check whether the irradiation angle of the far and near beams of the headlights meets the standards.

　　

Car headlights are also called the eyes of the car. The bulbs of the headlights mainly include vacuum lamps, halogen lamps, and xenon lamps. Vacuum lamps and halogen lamps are relatively cheap, but their service life is relatively short; while xenon lamps are expensive but can be used for 2500-3000 hours, and the lighting effect is better. For cars, car headlights not only play a role in modifying the appearance of the car, but also enable the driver to see the road clearly and avoid accidents when the visibility is low. Therefore, the maintenance and repair of car headlights is very important, and car owners should also pay attention to the use of car headlights in their daily lives.
