#AdaptiveHeadlights

On Tuesday, the National Highway Traffic Safety Administration (NHTSA) announced it had finalized a rule permitting automakers to install adaptive driving beam headlights on modern vehicles. Despite having pioneered automatic headlamps in the 1950s, the United States has been hesitant to implement automatic leveling and directional beams. In fact, imported vehicles equipped with adaptive headlights have been modified to adhere to regional safety laws for decades.

But the implementation of light-emitting diodes, high-intensity discharge lamps, and even upgrades to tungsten-halogen bulbs has made forward illumination substantially brighter. If you’ve been driving a while, you’ve probably noticed increased glare from oncoming vehicles (especially if you’re in an automobile that’s situated closer to the pavement). Directional beams are supposed to help alleviate the problem and have been getting more attention from U.S. safety regulators. However, that’s only part of the reason why the NHTSA suddenly feels better about approving them.

The National Highway Traffic Safety Administration announced earlier this month that it was willing to considering changing the rules that govern automobile headlights. Now in a comment period before its official review, the proposal would permit automakers to install and enable adaptive driving beam headlights on new cars sold in the United States. While some automakers are preparing themselves for the change, most have been ready for ages.

One one hand, this proposed change should help lousy drivers from burning out your retinas on a lonesome country road. But, by the same token, you may no longer have the delicious opportunity to blast them with the brights once they’re within a few feet of your car to let them know to lower those damned high beams.

Just kidding, that would be illegal. Federal mandates require all drivers to dim their headlights when approaching within 500 feet of an oncoming vehicle or when approaching a vehicle less than 300 feet ahead. Of course, nobody we know has ever witnessed this law being actively enforced — even though it’s probably as dangerous as moderate speeding infractions. Regardless, it’ll gradually become a non-issue if the rules change.
