Stern said other major contributors to the problem include headlight aim, which gets scant attention but is “far more important than the technology in the headlamp or how much light it puts out,” and the widespread availability of aftermarket LED bulbs and high-intensity discharge kits. “The lumen density, when it really aggregates and goes through the roof, that’s when our eyes will start to complain.” “What falls on your eyeball is what matters,” she said. Nisa Khan, president of IEM LED Lighting Technologies, a research and engineering company based in Red Bank, N.J. “It’s the concentration we need to pay attention to,” said M. Halogen lights put out 1,000 to 1,500 lumens, while high-intensity discharge lights and LEDs can measure 3,000 to 4,000 lumens. “Brightness” is not a term generally recognized by scientists and researchers, who refer instead to lumens, or the output of a light.

“If you choose to say, ‘I’m going to make the biggest, baddest light I can,’ you’re not paying attention to the receptors of another driver coming at you.” “It’s true that blue will allow you to illuminate farther,” he said. Mark Baker, the founder of an activist group called Softlights, said that, while the blue LEDs might be among the best for nighttime driving, that did not mean they were good for everyone. “Blue light is difficult for the human visual system to process because blue wavelengths tend to focus just ahead of the retina rather than on it,” he said. LED and high-intensity discharge headlights can appear more blue in their output spectrum than halogens, and they often provoke “significantly stronger discomfort reactions” than warm white or yellowish lights, Mr. or truck every time.” (Almost half of the 280 million registered passenger vehicles in the United States are S.U.V.s or pickup trucks.) “The eyes in the low car are going to get zapped hard by the lamps mounted up high on the S.U.V. “Tall pickups and S.U.V.s and short, small cars are simultaneously popular,” he added. Lights have gotten smaller over time, and “any given intensity appears brighter if it’s emitted by a smaller apparent surface versus a larger one,” said Daniel Stern, chief editor of Driving Vision News, a technical journal that covers the automotive lighting industry. The report described that percentage as a “sizable number” that “cannot be ignored.” As of March, more than a quarter of those tested received such a rating, the institute said.Ĭomplaints about headlight glare are not new, and date back at least 20 years.Īfter the National Highway Traffic Safety Administration sought comments from the public in 2001 about glare, it issued a report that said the 4,000 responses it received “was larger than those that NHTSA received on other safety concerns.”Ībout 30 percent of respondents said they had experienced “disturbing” nighttime headlight glare from oncoming traffic or from cars whose lights appeared in their rearview mirrors. When the institute, an independent, nonprofit research group, released its first headlight ratings in 2016, only one headlight system of more than 80 that were evaluated received a “good” rating. The trend toward improved headlight illumination has been fueled in part by manufacturers seeking higher safety ratings from the Insurance Institute for Highway Safety, Professor Kennedy said.

There is even a Facebook group and an online petition dedicated to banning blinding headlights. In the 2010s, LEDs became popular because they were longer-lasting, energy-efficient and perceived by automakers as sexy and modern.īut they also prompted complaints that they were too much of a good thing. High-intensity discharge lights, which cast a bright glow that approximates the spectrum of daylight, came in the late 1990s and early 2000s. Halogens, with tungsten filaments and better output, appeared in the late 1980s and early 1990s. “Sealed-beam” headlights were used from the 1950s through the 1980s, and generally offered poor light output.

Matt Kossoff, chief product officer of The Retrofit Source, an Atlanta-based distributor of lights for cars and trucks, said headlights had “absolutely gotten brighter.” It’s only a matter of time.” A lighting evolution gives rise to complaints DeVries said, referring to LED headlights. “If you’ve not been affected by them, you will be,” Mr.
