MUNICH—Headlight technology in the US is about to get smarter. When Audi’s Q9 SUV goes on sale here later this year, it will feature the automaker’s latest adaptive beam headlights, which manage the nifty trick of providing better, brighter illumination while minimizing glare for both the driver and other road users. Such technology is old hat to our European readers, but it’s finally debuting on our roads after years of lobbying and intensive, lengthy testing to satisfy the new federal regulations. And after trying out the headlights during a recent trip to Europe, I can say, “It’s about time.”
Despite America’s reputation as an innovation powerhouse, we have lagged behind Europe and Japan in automotive lighting technology for decades, thanks to 1960s-era regulations that allowed only low- and high-beam headlights, nothing else. For years, OEMs like Audi, BMW, Mercedes-Benz, Toyota, and Volvo lobbied the National Highway Traffic Safety Administration to allow them to bring more modern technology to these shores to no avail.
At first, it was laser high beams, which could project their beams much farther down the road than conventional halogen or xenon lights. Lasers are cool, but adaptive driving beam technology is even cooler. Each headlight is actually a multipixel LED, and by turning some of those pixels off, the headlight beam can be shaped to mask the light to selectively dim oncoming vehicles instead of switching to low beams.
