How to adjust the car's high beam and low beam lights?

Methods to adjust the car's high beam and low beam lights: The high beam can be switched to low beam by pushing the rotating lever towards the driver. There is usually a light adjustment device above the steering wheel. Move the switch towards the engine compartment position to keep the high beam on; pull it back one gear to turn off the high beam and restore the low beam; push it one more gear towards the driver for temporary high beam flashing, and the switch will automatically return to the low beam position when released. The car's high beam can improve driving visibility and expand the field of vision. When driving on roads without streetlights, the visibility range with high beams is much greater than with low beams. It is better to use high beams on roads with poor lighting conditions.
I remember last time when driving at night, my friend complained that my high beams were too bright and dazzling them, so I checked the manual to learn how to adjust them. Most cars have a vertical adjustment screw behind the headlight assembly. Park the car on a flat surface, ensuring the front is 3 to 5 meters away from a wall. I used a Phillips screwdriver to turn the screw, first turning on the low beams to check the beam position: the ideal height is about 75 centimeters from the ground at the center of the beam. If it's too low, the road won't be clear enough; if it's too high, it will dazzle others. After adjusting the low beams, test the high beams to ensure they shine far without scattering. Don't use too much force during the process, as overtightening the screw can damage the bulb or mechanism. After the adjustment, a night test drive showed much clearer visibility. If you're not familiar with the process, it's best to ask a repair shop for help to avoid mistakes that could affect safety, since lighting is crucial for nighttime driving safety.
The key to headlight adjustment is balancing illumination range and avoiding glare. Many models have vertical and horizontal adjustment screws on the headlights, located at the rear cover holes, operable with an Allen wrench or screwdriver. Before adjusting, ensure the vehicle is on level ground with the headlight switch on, preferably in low beam mode as it determines the base height. The method involves parking 5 meters from a wall to measure the beam, where the center point should be about 20% lower than the headlight height proportion. Turn the screw clockwise to raise and counterclockwise to lower; adjust the high beam as secondary auxiliary light to avoid excessive illumination that may violate regulations. Some modern cars come with automatic leveling systems, but manual adjustment is more reliable. Don't forget to check regulations, as excessive light may result in fines.
