WG9719720001 Headlamps refer to lighting devices installed on both sides of the head of a car for night driving roads. There are two-lamp system and four-lamp system. The lighting effect of the headlights directly affects the operation and traffic safety of driving at night. Therefore, traffic management departments around the world generally stipulate the lighting standards of automobile headlights in the form of laws to ensure the safety of driving at night.

In the use of automobiles, the requirements for headlights are: not only have good lighting, but also avoid dazzling oncoming drivers. Therefore, the following points should be paid attention to when using headlights:

(1) Keep the headlamp lens clean, especially when driving in rainy and snowy weather, dirt and other dirt will reduce the lighting performance of the headlamp by 50%. Some models are equipped with headlight wipers and water jets.

(2) When two cars meet at night, the two cars should turn off the high beam of the headlights and switch to the low beam when they are 150m apart to ensure driving safety.

(3) In order to ensure the performance of the headlights, the beam of the headlights should be checked and adjusted after replacing the headlights or every 10,000km of the car.

(4) Regularly check the bulbs, circuit sockets and grounding for oxidation and looseness to ensure good contact performance of the connectors and reliable grounding. If the contact is loose, when the headlight is turned on, a current impact will be generated due to the on-off of the circuit, which will burn out the filament. If the contact is oxidized, the brightness of the bulb will decrease due to the increase in the voltage drop of the contact.
