What lights should usually be turned on when driving at night?

[McAmy]

When driving at night, it is common to turn on the width marker lights and low beam headlights. Below is a detailed introduction about width marker lights and low beam headlights: 1. Width marker lights: Width marker lights are mainly used to indicate the presence and approximate width of a vehicle, alerting oncoming and following vehicles to facilitate their judgment during meetings and overtaking. Installed at the edges of the vehicle's roof, they indicate both the height and width of the vehicle. Safety standards require vehicles taller than three meters to be equipped with width marker lights. 2. Low beam headlights: Low beam headlights are designed for close-range illumination. They have a wide illumination range but a short illumination distance, and the focus cannot be adjusted. On one hand, low beam headlights have an illumination distance of about 30 meters. On the other hand, they have a very distinct beam cut-off line between light and dark.
