Which means virtually every headlight on the road in New York potentially violates the law.įederal limits are orders of magnitude higher, and in a different measurement all together.ĭepending on the lighting system of the vehicle, headlights are limited to about 20,000 to 75,000 candela, according to Federal Motor Vehicle Safety Standard No. For comparison, one candlepower equals the light produced by a single candle.Ī typical lamp in someone's home emits about 100 to 140 candlepower. New York's vehicle and traffic law limits the power of headlights to 32 candlepower, an obsolete unit of measurement for a light's intensity. Many states have laws that limit their power as well. When HIDs were introduced in 2004, NHTSA had ordered 24 HID companies to either cancel sales or issue recalls by October of that year, because the lights violated regulations.īut federal regulations aren't the only limits on headlight brightness. "Older drivers also have a longer recovery time for their vision to return to normal after experiencing glare," Trick said.įederal regulations limit headlight brightness. Specifically the National Highway Traffic Safety Administration (NHTSA) polices bulb makers. A need which compounds with another problem older drivers face. That seemingly darker night effect creates a need for more light, Trick said. "As you get older, your pupils let in less light, which makes everything seem darker," Trick said. Trick sees it as a two-part problem of aging. Professor Lana Trick - a distracted driving expert from University of Guelph, Ontario, Canada - explained how an aging population in places like the U.S., Canada and Europe causes part of the situation drivers face at night. "Any oncoming light completely blinds me." How the lights powered upĪutomotive lighting for many years remained the same then, like a flash of technological lighting, lit up the night.Įssentially the issue arose from the collision of three separate issues: Antiquated regulations, rapidly advancing technology and an aging population all converged on the automotive lighting world. "At 78, I've given up driving at night totally," said the U.S. Longtime Piermont resident Ed Beach, who now lives in Tennessee, struggles in his new state with headlight brightness. Whether drivers complain about the color or intensity, many blame themselves, and while age plays a part, but that's only a piece of the puzzle. Kesselman talked about experiencing what experts call discomfort glare, a feeling of annoyance caused by high luminance in their field of view. "I have a terrible time with them on the Palisades Parkway," Kesselman said. Jessica Kesselman is one of those drivers struggling on nighttime drives with exceedingly bright headlights. From dark roads such as the Taconic State Parkway, to brighter Interstates, like I-87, this new generation of lights can produce similar glaring effects during rush hour traffic in the dark. In New York - and particularly on the dark roads of the Hudson Valley - drivers are facing an onslaught of powerful headlight glare. Leaps in lighting technology combined with confusing regulations and antiquated laws have coalesced into an everyday evening frustration, one that has had more than one driver asking themselves behind the wheel, "Why does that guy have his brights on?" Increasingly, this is becoming a regular reaction by motorists from coast to coast, particularly older drivers, as they navigate dark roads. Hills rise and fall amid as a line of cars zips along the tree-lined roadway. But faces wince and heads turn away when a car crests the top of the opposite hill, its headlights dazzling. A crisp December evening, your car rolls along the Taconic State Parkway, headed home.
