The article explores different types of car headlights to find the best balance between seeing far ahead and reducing glare for other drivers. Tests showed that brighter headlights allow drivers to see more, but they also create more glare for oncoming cars. The researchers tested traditional and newer headlamp designs, like quartz iodine headlamps, to measure how far drivers could see. They found that a headlamp with higher candlepower gives a wider field of vision but also causes more glare. The study aims to find a headlamp beam pattern that offers the best compromise between seeing distance and reducing glare.
