What is the purpose of the Passat's width indicator lights?

[Kiara]

Commonly known as small lights. Literally, "indicator" means warning; "width" refers to the outline, so width indicator lights are warning lights on a vehicle, used to alert other vehicles. These lights are usually installed along the edges of the car's roof, indicating both the height and width of the vehicle. Safety standards require that vehicles taller than three meters must be equipped with width indicator lights. Front width indicator lights: The front width indicator lights generally emit white light, making it easier for oncoming vehicles to discern the car's width and position, thereby enhancing safety. Simply put, the primary function of width indicator lights is not aesthetics! It is to improve the vehicle's visibility, making it easier for other "road users" to see the car and be aware of its approach. Rear width indicator lights: The rear width indicator lights typically emit red light to enhance light penetration, making it easier for following vehicles to spot the car ahead in poor visibility conditions, thus avoiding accidents caused by delayed detection of the vehicle in front.
