What lights to use on sharp turns?

[Abigail]

When driving through sharp turns, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, motor vehicles should alternately use high and low beams to signal. Here is a brief introduction to high and low beams: High beam: The intensity of the light is adjusted based on the distance of the filament. The high beam is focused, emitting parallel light that is more concentrated and brighter, capable of illuminating distant and high objects. Low beam: The low beam is positioned beyond the focal point, between 1x to 2x the focal distance, emitting light in a divergent pattern that illuminates a larger area at close range. The illumination distance of the low beam is approximately 30-40 meters.
