What is the difference between width lights and contour lights?

[Verona]

Width lights and contour lights are the same; width lights are also known as contour lights. These are lamps installed at the front and rear high points of a vehicle, similar to anti-collision lights on aircraft wingtips. They are primarily used during 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, width lights are white at the front and red at the rear. Types and functions of vehicle lights include: 1. Brake lights: Warn vehicles or pedestrians behind; 2. Turn signals: Alert surrounding vehicles and pedestrians; 3. License plate lights: Illuminate the license plate at night; 4. High beams: Check distant road conditions; 5. Low beams: Provide clear visibility of the road ahead; 6. Fog lights: Offer strong penetration in fog, making the vehicle more noticeable; 7. Daytime running lights: Increase visibility to other traffic participants.
