What is a position light?

[MacLondon]

Position lights are width-indicating lights, located at the high positions on the front and rear of the vehicle. The front position lights are beside the two headlights, while the rear position lights are usually integrated with the brake lights. Position lights are primarily used during driving in dusk, overcast, rainy, or foggy conditions to indicate the vehicle's width and height, helping other drivers judge relative positions and vehicle size during overtaking or meeting. Typically, the color of position lights is white at the front and red at the rear. Functions of position lights: 1. They make the vehicle more easily identifiable during daytime driving; 2. When the vehicle is turning, activating the position lights alerts surrounding vehicles and pedestrians; 3. They provide road illumination during nighttime driving.
