Headlights are installed on both sides of the car head for lighting the driving road at night. There are two lamp system and four lamp system. Because the lighting effect of headlamp directly affects the operation and traffic safety of driving at night, traffic management departments all over the world have stipulated their lighting standards in the form of laws.

Generally, the four lamp system is adopted for automobile headlamps, and the main reason for the failure of this four lamp system is generally the failure caused by the use of high-power bulbs; Of course, many car owners have bought some bulbs of poor quality on the market to replace, resulting in insufficient wattage; Some of them deliberately replace high-power bulbs in order to increase the wattage and brightness of the headlamp; These are the causes of automobile headlamp failure.

These causes of automobile headlamp failure are basically the improper use of bulbs. Some car owners may not take this seriously, but the fact is that these practices will cause damage to other auto parts. For example, the lamp is burnt out and the battery is damaged, which may lead to a short circuit of the wire and cause a car explosion; Therefore, we need to treat the headlamp failure seriously in order to prevent accidents.
