How are the headlights assessed in terms of brightness?

Evaluating the brightness of headlights focuses on their ability to provide adequate illumination for safe driving during nighttime conditions. This assessment ensures that drivers can effectively see the road, obstacles, and other vehicles, thus enhancing overall safety. It's essential for headlights to emit enough light to illuminate the driving path without causing glare to oncoming drivers.

While wattage, adjustability, and matching manufacturer specifications are important factors regarding headlights, the primary criterion for their assessment is their capability to ensure visibility and safety during night driving. Sufficient brightness can significantly reduce the risk of accidents and increase a driver's ability to respond to unforeseen circumstances on the road.
