Under what circumstances does position lamp open; Is the position indicator a width indicator?

The position lights on the car are the lights on the edge of the front and rear. There are also position lights on the roof and side of large trucks. Position lamp, literally, "instruction" means warning; "Outline" means outline, so the outline lamp is a warning sign lamp and a signal lamp to remind other vehicles to pay attention. The edge mounted on the top of the car can indicate the height and width of the car at the same time.

Safety standards stipulate that cars with a height of more than three meters must be equipped with position lights. The color of position lamp is white before and red after.
