What are vehicle width indicator lights?

[SarahLynn]

Vehicle width indicator lights refer to the front position lights and rear position lights on a vehicle. They are primarily used to indicate the presence and approximate width of the vehicle, facilitating judgment by other vehicles during passing and overtaking. Therefore, width indicator lights serve as warning lights, signaling other vehicles to take notice. Safety standards mandate that vehicles with a height exceeding three meters must be equipped with width indicator lights. These lights are used during driving in conditions such as dusk, overcast days, or rainy and foggy weather to indicate the vehicle's width and height, helping other vehicles determine relative positions and sizes during passing and overtaking. Typically, the color of width indicator lights is white at the front and red at the rear.
