Should I use auto or low beam at night?

[ColemanRose]

You can use either auto or low beam at night, because if you switch the light control knob to the auto position, the headlights can automatically switch between high beam and low beam. Auto refers to automatic headlights, which are driving lights that can turn on automatically. Automatic headlights use a photosensitive sensor to detect the intensity of light and decide whether to turn on the headlights. Automatic headlights are controlled by a central intelligent control box that determines changes in light brightness based on a light sensor located behind the interior rearview mirror, automatically turning on or off the parking lights and low beams. The advantage of automatic headlights is that they can independently turn on and off the headlights based on the intensity of ambient light.
