Modern LED headlights are significantly brighter and more glaring than traditional halogen bulbs, creating dangerous driving conditions, lighting experts report. The newer lights produce an intense, concentrated beam that is bluer and more disorienting, particularly affecting older drivers. “Headlights are getting brighter, smaller and bluer. All three of those things increase a particular kind of glare. It’s called discomfort glare,” said Daniel Stern, chief editor of Driving Vision News.
