Brighter, no glare headlights are coming. Here's what we know:
...The National Highway Traffic Safety Administration, which sets standards for vehicle safety, is working on a rules for a new technology called adaptive driving beam or ADB lights. Automakers and suppliers are waiting impatiently to offer the superior systems they already sell in much of the world...
...ADB lights combine three features that are innovative, but have been proven driving millions of miles in heavily regulated, safety conscious markets.
They consist of:
A. Arrays of many LED lights
B. Full-time high beams
C. Systems to direct light away from other drivers' eyes and toward street signs, or potential obstacles like a deer by the side of the road.
"We're talking about a safety system with provable benefits," Morgan [senior vice president for global product development at lighting supplier Varroc] said. "We have reams of data from Europe, but we don't know when it'll be legal in the U.S. It's a huge shame."
The latest ADB lights use digital cameras to detect oncoming vehicles, street signs, etc. Software turns selected LEDs on or off, keeping light out of oncoming drivers' eyes and illuminating signs, pedestrians, detours, etc....
Other up and coming technologies include:
Lasers to supplement LED high beams, increasing the range of headlights up to 50%
Micro mirrors on LED chips, which could allow personalized signature lights and more.
Personalized and driver-programmable lighting will require more regulation, Morgan said, "We don't want to turn the roads into discotheques."...
...The same systems that allow ADB to avoid drivers' eyes should be able to adjust automatically for towing...
...Improvements in lightweight materials for lenses is reducing the likelihood of clouding and fogging over time....
The first sentence quoted above is inaccurate: "Brighter, no glare headlights are coming." ADB will have some glare, at levels that are typical for traditional low beam headlights. ADB will have low beam levels of glare for oncoming traffic, but with high beam levels of illumination as seen from the driver's seat.
