How to Adjust Car Low Beam Lights for Optimal Effect?
2 Answers
Here are the steps to adjust car low beam lights: 1. Enter the driver's compartment and locate the headlight height adjustment knob on the lower left side behind the steering wheel. 2. The headlight height adjustment knob has multiple gear positions, divided into four levels: 0/1/2/3. 3. Position 0 is the lowest height setting and also the default low position. 4. Position 1 is slightly higher than position 0 and can be adjusted according to road conditions. 5. Position 2 is slightly higher than position 1, but be careful not to affect oncoming traffic when using it. 6. Position 3 is the highest setting and can be used in suburban areas without streetlights. 7. The high beam control lever is located on the left side behind the steering wheel.
I usually pay attention to practicality when driving and have some experience with adjusting low beams. Generally, I choose to do it at night on a level surface, positioning the car about 5 meters away from a wall. First, I measure the height of the headlights and mark an equal-height line on the wall. After turning on the low beams, I rotate the adjustment screws behind the headlights to align the upper edge of the beam just 2-3 cm below the marked line. This adjustment works exceptionally well: it ensures the light covers about 30 meters of the road ahead without dazzling oncoming drivers. Horizontal adjustment is also crucial—I make sure the two beams overlap about 2 meters ahead and diverge slightly outward for better roadside visibility. I recommend checking the headlight height monthly, especially after carrying heavy loads or many passengers.
