What are width indicator lights?

[LeRylee]

Width indicator lights, also known as clearance lights or commonly referred to as small car lights, are installed at the highest points at the front and rear of a vehicle. Their purpose is to indicate the presence and approximate width of the vehicle, aiding other drivers in making judgments during passing or overtaking. The width indicator lights are positioned at higher points on the front and rear of the vehicle; the front width indicators are located beside the headlights, while the rear ones are integrated with the brake lights. The main uses of width indicator lights include: 1. Temporarily parking by the roadside at night—width indicator lights should be turned on; 2. Serving as driving lights on well-lit roads without needing to use headlights; 3. Activating width indicator lights during rain, snow, fog, nighttime, or other conditions with poor visibility to alert passing vehicles.
