How to adjust the height of high beam lights?

Methods to adjust the height of high beam lights: 1. Open the engine hood, locate the adjustment knob for the headlight angle near the headlight base. These knobs are usually designed with a plastic hexagon shape and can be adjusted using a hex wrench of the corresponding size; 2. Using a standard sedan as a reference, if the front vehicle's license plate is installed on the trunk rather than the rear bumper, when the distance between the vehicles is more than two meters, the upper edge of your vehicle's light beam should not illuminate the other vehicle's license plate. High beam lights adjust the intensity of the light based on the distance of the filament. The high beam light is focused at its focal point, emitting light that is parallel and highly concentrated, providing greater brightness and the ability to illuminate distant and high objects.
Adjusting the height of the high beam is quite simple, as many cars have dedicated adjustment mechanisms. For example, my car is an older model with manual adjustment. You just need to open the hood, locate the height adjustment screw hole on the headlight assembly—usually a hex or Phillips screw—and use the provided tool or a regular screwdriver. Turn clockwise to raise the beam and counterclockwise to lower it. It's best to do this at night in an open area, aiming at a wall about 10 meters away to create a reference light line. Adjust until the beam is at a suitable horizontal level to avoid blinding oncoming traffic. Some models even have a knob near the dashboard for easier height control. The key is to refer to your vehicle's manual, as different brands vary significantly. After adjustment, test it on the road. If the beam still seems too short or uneven, the bulb might be old and need replacement. I always do it myself to save a trip to the dealership and the cost.
