What are the maintenance methods for car headlights?
Car headlights are an important part of the car and an important lighting tool for night driving. In the daily use, the car headlights also need regular maintenance. This will maintain the brightness and longevity of the headlights.
According to the data, 25% of the total mileage of the vehicle is driven at night and under natural light. In this case, personal injury accidents account for 33% of the total number of traffic accidents and 50% of deaths. It happened at night.
The headlights have two modes of high beam and low beam. The low beam lights are used in the city or in the car. The high beam illumination angle is high, the illumination is farther, the vision is wide, and it is suitable for roads outside the city. Reasonable use of the headlights should be done: use low beam when the car is going to be used, and when passing through the intersection and overtaking, it should be prompted to change the far and near light.
Car headlight maintenance project:
1. Check the sealing of the headlights
If there is moisture intrusion in the headlamps, the service life of the bulb will be reduced. For this reason, attention should be paid to the sealing of the headlamps. If the seal between the lens and the mirror is damaged, replace it in time.
2, cleaning the mirror
The mirror of the semi-enclosed headlamp turns black and should be replaced when the luminosity is reduced. If there is only dust on the mirror, it can be replaced with compressed air instead of replacing it. For mirrors that cannot be blown, if the mirror coating material is chrome-plated, due to the high hardness, deer skin absolute ethanol (content 95% or more) can be gently wiped from the inside of the mirror to the outer spiral. .
If the mirror is silver-plated or aluminized, due to its poor hardness, it can only be cleaned with clean cotton and hot water when cleaning. Never wipe it to avoid damage to the mirror coating.
Some mirror surfaces are pre-coated with a thin, transparent protective film, so be careful not to damage them when cleaning. If the mirror is often dirty, the sealing rubber ring is damaged and must be replaced. After wiping or cleaning the mirror, be sure to dry it and reinstall it, and pay attention to the correct position.
3, cleaning the bulb
When there is dust on the halogen bulb, it can be scrubbed with absorbent cotton impregnated with ethanol (90%). When scrubbing, be careful not to let the lights go out and the bulbs are still hot. After cleaning, it should be dried instead of dried. Do not touch the lamp with your hand or rag, immediately turn on the power, otherwise it will lose its luster or even recover.
4, adjust the beam direction
During the running of the car, due to the vibration of the body, the direction of the beam is deviated, so there is a special inspection of the direction of the headlights during the annual inspection. During regular maintenance, technicians may also be required to check and adjust the direction of illumination. Generally, the screen method is used for adjustment. Before the inspection, care should be taken to ensure that the tire pressure reaches the standard value.
5. How long does the car headlight bulb change?
According to the car maintenance book, the brightness of the headlight bulb will be weakened every time it is replaced by 50,000 kilometers or about 2 years.
