What is the function of the vehicle's width indicator light?

[ColtonMarie]

Width indicator lights, also known as clearance lights, are primarily used to indicate the presence and approximate width of a vehicle, aiding other vehicles in judging during encounters and overtaking. Below are situations where width indicator lights should be turned on: 1. Driving in foggy conditions: Due to reduced visibility and blurred sight, it is necessary to turn on the width indicator lights along with the fog lights to provide a clear warning to other road users. 2. Rainy weather: They serve as a warning signal to both preceding and following vehicles, helping to minimize potential harm. 3. Night driving: It is mandatory to turn on the clearance lights. Traffic regulations require that rear tail lights and width indicator lights be activated during night driving to alert following vehicles. 4. Dusk: In the absence of streetlights and when vehicle lights are not very bright, it is still essential to turn on the width indicator lights for safety, ensuring other vehicles can see your car.
