What are the front and rear position lights on a vehicle?

[VanIsaac]

Front and rear position lights on a vehicle refer to the lights that indicate the vehicle's position, also known as width marker lights. When illuminated, they outline the vehicle's silhouette. These lights are primarily used during dusk, overcast days, or in rainy/foggy conditions to display the vehicle's width and height, helping other drivers judge relative positions and vehicle dimensions during passing or overtaking maneuvers. Typically, position lights are white at the front and red at the rear. Other commonly used vehicle lights include: 1. Headlights - installed on both sides of the vehicle front for road illumination during nighttime driving; 2. Turn signals - activated when changing direction to alert surrounding vehicles and pedestrians.
