What are Width Indicator Lights?
2 Answers
Width indicator lights, also known as contour lights or commonly referred to as parking lights, are installed at the highest points of the front and rear of a vehicle, similar to the anti-collision lights flashing at the wingtips of an aircraft. These lights are primarily used during dusk, overcast days, or in rainy and foggy weather to indicate the width and height of the vehicle, helping other drivers judge the relative position and size of the vehicle during overtaking or when passing each other. Typically, the front width indicator lights are white, while the rear ones are red. Additional information: Below is a partial introduction to the differences between contour lights and width indicator lights: 1. Contour Lights: Contour lights are used during nighttime driving to make the vehicle visible to others. Also known as width indicator lights or parking lights, they serve as warning lights. When illuminated at night, they help other vehicles perceive the length and width of the car to avoid traffic accidents. 2. Width Indicator Lights: Width indicator lights are warning lights used to alert other vehicles, also referred to as contour lights or parking lights. Another term for them is evening driving lights.
I've been driving for over twenty years, and the position lights are small lights installed on both sides of the car, usually integrated with the headlights or taillight clusters. They are primarily used during nighttime, rainy days, or in low-light conditions to help other vehicles or pedestrians see the width and outline of the car, preventing accidental collisions. Especially in parking lots or narrow roads, failing to turn on the position lights can make a car easily overlooked. I remember once at dusk, a car without its lights on almost scraped my side mirror. Don’t forget to turn them on when parking—they consume little power and enhance safety. They are typically located at the edges of the vehicle for easy maintenance.
