How to adjust the headlights of BYD F3?
2 Answers
BYD F3 lever-type headlight adjustment is as follows: 1. First prepare a flashlight (the adjustment point for F3 is in the engine compartment, which is hard to locate), a tape measure, and a screwdriver. 2. The center height of the light's hotspot, which is the height to be adjusted = the height of the headlight from the ground × 0.95. For the F3, the headlight is about 70 cm from the ground, so the calculated adjustment height is 66.5 cm. This height ensures the light lands at about 100 meters on the road, providing the best illumination. 3. Drive the car to a distance of about 5 meters from a wall, draw a horizontal line at 66.5 cm on the wall, and then start adjusting. 4. The two outer adjustment points control the left-right position of the light, while the two middle ones adjust the up-down position. If the right headlight is slightly tilted towards the center, turn the adjustment gear on the right headlight counterclockwise. It's best to mark a reference point on the wall. 5. After adjusting the left-right position, proceed to adjust the height of the light. Turn the gear near the center position counterclockwise to lower the light gradually, or turn it clockwise to raise it. The up-down adjustment is relatively simple. 6. Use the height of the other headlight as a reference to clearly see the adjustment of the light's height. Adjust the center of both headlights' hotspots to the horizontal line on the wall to complete the adjustment.
Last time I adjusted the headlights on my BYD F3, I did it in the garage. The whole process wasn't complicated: First, find a flat surface to park the car, with the front facing a wall a few meters away. Then open the hood, locate two small screw holes behind the headlight module - one controls the vertical angle of the light, the other adjusts the horizontal position. I used a Phillips screwdriver to slowly turn them, testing from bottom to top while observing the changes in the light projection to ensure the beam wasn't too high or too low. Remember to test it at night with low beams to check the effect - too high might dazzle other drivers, too low won't illuminate far enough. After adjustment, driving at night became much safer, and I saved money by avoiding the dealership. During regular maintenance, check the headlights as screws can loosen over time - just readjust them when needed. DIY saves time and effort while teaching new skills.
