Should Headlights Be Adjusted Higher or Lower?
2 Answers
Whether headlights should be adjusted higher or lower depends on the situation. Here is some information about headlight adjustment: 1. Adjustment: When the car is empty, set it to 0, which is the highest point. When fully loaded with passengers, adjust to 2 or 3, and when the trunk is fully loaded, adjust to 4 or 5. Don't think it's too low; it's for safety. The highest point should align just below the windshield of oncoming vehicles. Headlight height adjustment guidelines: 'For three passengers, use setting 3; for two passengers, setting 2; for one passenger, setting 1; and for no passengers, setting 0.' 2. Vehicle factors: The height of the car changes with suspension travel. Therefore, when the vehicle's body height changes, it's necessary to appropriately adjust the headlight height to ensure driving safety.
I've been driving for over 20 years, and my experience with headlight height adjustment is to set them slightly lower. If they're too high, they can easily dazzle oncoming drivers at night, impairing their vision of the road and increasing the risk of collisions. On the other hand, if they're too low, the light only illuminates the immediate area, making it harder to spot obstacles in advance on highways. My suggestion is to first find a parking lot, park the car on level ground facing a wall, and mark the position of the light beam—the standard height should be about halfway between the centerline of the tire and the center of the headlight housing. When adjusting, use a wrench to turn the adjustment screws, taking it slow and steady. Don't forget that in the city, streetlights provide ample illumination, so you don't need the beams too high—otherwise, you could face hefty fines if caught by traffic police. Always prioritize safety; after adjusting, take a test drive to ensure the light coverage is even and adequately illuminates the road ahead.
