What position should the car headlight height adjustment be set to, from 0 to 3?

The headlight height adjustment can be selected based on the load. The higher the value, the higher the light beam will be. However, an excessively high light beam can easily cause glare for oncoming drivers. Generally, setting the headlight height adjustment to position 0 is sufficient. Precautions for car lights: Precautions for headlights: Position 0 is suitable when there are passengers in the front seats and the trunk is empty. Position 1 is suitable when the vehicle is fully loaded with passengers but the trunk is empty. Position 2 is suitable when the vehicle is fully loaded with passengers and the trunk is full. Position 3 is suitable when the vehicle is fully loaded with passengers and the trunk is full. When visibility is between 200m and 500m, it is necessary to turn on the low beam, width indicator lights, and tail lights, and the speed should not exceed 80km/h. Additionally, a following distance of at least 150m must be maintained from the vehicle ahead in the same lane. Additional notes on car lights: Additional car lights refer to the lighting fixtures on the vehicle, which serve as tools for road illumination during nighttime driving and as signaling devices for various driving indications. These typically include headlights, tail lights, turn signals, etc. The most common types of car lights are halogen lamps, xenon lamps, and LED lamps.
That 0 to 3 adjustment knob for car headlights is quite particular in my opinion, after driving for over 20 years. The 0 setting usually adjusts to the highest position, with the light shining far, suitable when the trunk is fully loaded or the back seats are full, preventing the lights from shining too low when the car tilts backward. The 3 setting adjusts to the lowest, with the light shining near, suitable for an empty car or when only the front seats are occupied, avoiding dazzling oncoming traffic. For daily driving, I recommend setting it between 1 and 2, providing comfortable visibility without being too bright on flat roads. Remember to test the light height against a wall when parked; if the center of the light spot is within half a meter below the headlight height at about 10 meters, it's safe. Don't underestimate this adjustment—it directly affects nighttime driving safety, reducing the risk of rear-end collisions or accidents. I always check it before highway trips. Overall, the 0 to 3 settings are simple tools designed for different loads, and adjusting them correctly ensures peace of mind.
