How to Maintain Headlights?
1 Answers
There are several methods for headlight maintenance. Here is some relevant knowledge: 1. Check the sealing of the headlights. If moisture enters the headlights, it will reduce the lifespan of the bulbs, so it is important to inspect the sealing of the headlights. 2. Clean the bulbs. If there is dust or dirt on halogen bulbs, you can use degreasing cotton soaked in ethanol (90%) to wipe them. When cleaning, avoid doing so immediately after the headlights have been turned off and the bulbs are still hot. After cleaning, let the bulbs air dry instead of wiping them, and do not turn on the power immediately after touching the bulbs with your hands or a cloth, as this may cause them to lose their luster or become irreversibly damaged. 3. Adjust the beam direction. During driving, the vibration of the car body may cause the beam direction to deviate, so there is a special inspection for headlight beam direction during annual vehicle inspections. 4. Headlight bulbs also need to be replaced regularly. According to car maintenance manuals, bulbs should generally be replaced every 50,000 kilometers or every two years, as the brightness of the bulbs will diminish over time. It is best to have them checked at a 4S shop. If the brightness is indeed insufficient, it is recommended to replace the bulbs, preferably both sides at the same time to avoid uneven brightness. 5. Replace aging headlight covers promptly. Environmental factors can cause headlight covers to age, which can reduce the brightness of the headlights by more than 50%. Dirty or aging covers can also make the light appear blurry, causing dizziness.
