Why are the high beams of a car lower on the left and higher on the right?

[Hugh]

In China, vehicles drive on the right side of the road, with oncoming traffic on the left. The left headlight is adjusted to a lower position to ensure the visibility of oncoming drivers, effectively reducing the occurrence of accidents. The right headlight is set higher to illuminate farther distances. On one hand, this helps drivers detect pedestrians ahead earlier, ensuring safer driving. On the other hand, it also alerts non-motorized vehicles or pedestrians to the presence of approaching vehicles from behind, allowing for a safety buffer. Below are some related details: 1. High beams: High beams adjust the intensity of light based on the distance of the filament. The high beam is focused at its focal point, emitting parallel light that is more concentrated and brighter, capable of illuminating distant and high objects. Low beams are positioned beyond the focal point, between 1 to 2 times the focal distance, emitting divergent light that covers a larger area at closer distances. 2. Precautions: When driving at night, it is important to use lights appropriately to avoid compromising the safety of other drivers.
