Worse, roughly 75% said that this visual epidemic has gotten worse since 2016.Some vehicles are worse offenders than others, but the data is clear.Source: AutoGuideSource: AutoGuideTake, for example, the 2017-2024 Nissan Titan. The Insurance Institute for Highway Safety (IIHS) found that the truck's headlights produce 615% more glare than the acceptable limit, but that somehow doesn't mean the lights are illegal. Meanwhile, the BMW X5's headlights were almost 678% over the accepted limit.AdvertisementAdvertisementObviously it's not only the IIHS that knows this is an issue. Those above-mentioned numbers come by way of U.S.-based eyeglasses company Overnight Glasses, which analyzed the 257 vehicles in the IIHS' test to make sense of heads and tails.Source: AutoGuideSource: AutoGuideIt's more complicated than that, though. Headlight height plays a big factor, which is why a taller vehicle's headlights will look brighter and cause more glare in your mirrors (given all other parameters are equal) than one that is lower.Massive, skyscraper-height modern pickups are the worst offenders, and the case of the Titan epitomizes that. Right behind the Titan on the eyeball offender list? Chevy's Silverado 1500 and the Ram 1500. No surprise there.AdvertisementAdvertisementWhat's really problematic is that you can drastically exceed the accepted legal limit for headlight brightness and yet still sell the vehicles in question without issue in the USA. Manufacturers are constantly finding ways to skirt the law, and though this doesn't necessarily encompass "legality" per se, it's indicative of how vehicle design impacts everyone.Become an AutoGuide insider.
