Smart Headlights Finally Trickle Down to Cars in the U.S.

If you’ve shielded your eyes from oncoming headlights that seem brighter than a supernova — and who hasn’t, lately? — there is new technology that should dazzle drivers.In a good way.For about a decade, cars all over the world have had high-tech smart headlights that can steer light away from oncoming traffic while surgically illuminating the pavement farther down the road.

They’re better for you, the driver, and they’re better for the drivers in front of you.They have finally been approved for American roads, and carmakers are slowly incorporating them into new models.Even with the approval of these adaptive driving beam headlights, or A.D.B.s., it will take years before enough vehicles are equipped with the tech to make a significant difference.

But at least there’s light at the end of the tunnel.They can only help.According to Federal Highway Administration data, half of all traffic fatalities happen after dark, but only one-quarter of driving happens at night.Adaptive headlight technology employs dozens of individually controlled LEDs that can be switched on or off, and even dimmed, to create precise light patterns.

It allows the clusters to cast illumination farther than typical LED lighting while masking it from the eyes of oncoming travelers.Following a vehicle in the same lane? The smart headlights can focus lumens on either side of it while screening the glare away from its rearview mirror.Gathering information from cameras, accelerometers, steering wheel angle sensors and GPS data, the lights can pinpoint their illumination.

This is different from automatic high beams or “steerable” lighting that physically pivots to match steering wheel inputs.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.If you are in Reader mode please exit and log into your Times account, or subscribe for all of The Times.Thank you for your patience whi...
