How to adjust the headlights of BYD F3?

To adjust the headlights of BYD F3, first park the car 7.6 meters away from a wall and turn on the headlights facing the wall. Adjust the light projection position in real-time based on the light projection on the wall. Low beam adjustment: Turn on the low beam, and a clear cutoff line will be projected on the wall. Use a cross screwdriver to adjust the left-right and up-down screws of the low beam, aligning the center turning point of the low beam cutoff line with the low beam mark on the wall. High beam adjustment: Turn on the high beam and use a hex socket to adjust the up-down and left-right screws of the high beam. Since the high beam does not have a cutoff line, two light spots will be projected on the wall. Adjust the center point (i.e., the brightest spot) of the high beam spots to align with the high beam mark on the wall. The BYD F3 is an A+ class sedan produced by BYD Auto, featuring a stylish and elegant exterior, a simple and neat interior design with a fresh light color scheme, and comprehensive and rich configurations.

As a long-time owner of the BYD F3, I usually adjust the headlights myself because the beam tends to misalign over time, affecting visibility. First, park on a level surface, pop the hood, and check for small screws or adjustment holes at the back of the headlights—the F3 typically has screws for both height and lateral alignment. I use a Phillips screwdriver to turn them gradually, testing the beam position against a wall or garage door after each small adjustment to ensure it’s centered. Avoid setting it too high to prevent dazzling other drivers, which is crucial for road safety and avoiding fines. I recommend doing this at night for better visibility, then taking a short drive to confirm even road illumination. If screws are rusty, a spritz of WD-40 helps. Make it a habit to check every six months for safer night driving. Wear work clothes to avoid staining the interior, and keep a basic toolkit handy.

I find adjusting headlights to be quite an interesting DIY task, saving the hassle of going to a shop. The F3's headlight adjustment isn't complicated - just locate the adjustment screws behind the headlight cover, usually there are two or three controlling up/down and angle. Use a small screwdriver or special tool, turn counterclockwise a bit to raise the beam, clockwise to lower it. Make sure the engine is off during adjustment to avoid electric shock. Mark a reference line on a flat wall 5 meters away - the adjusted beam shouldn't exceed this line. Don't worry if it's not perfect on first try, just repeat until the illumination feels even. Test the results during actual driving, especially checking if the lighting keeps up during turns. Keeping these small tools in your toolbox saves money, builds knowledge, and prevents misaligned lights from affecting oncoming traffic safety.

The angle of headlights directly affects nighttime driving safety. My F3's headlights became misaligned after prolonged use, which is quite dangerous. Therefore, I learned the adjustment method myself: first locate the screw holes behind the headlights, then gently turn them with a tool, testing whether the beam clearly illuminates the road without causing glare. The adjustment process is quick—only make small changes at a time and avoid overdoing it. After finishing, it's best to test the effect by driving on a safe road at night. This helps eliminate accident risks and complies with regulations. If you can't find the screw positions, check the manual or ask a friend for help.
