Feds legalize new lifesaving headlight tech

Anyone who has ever been temporarily blinded by high-beam headlights from an oncoming car will be happy to hear this. Audi's lighting tech can be focused enough to project images on a wall. U.S. highway safety regulators are about to allow new high-tech headlights that can automatically tailor beams so they focus on dark areas of the road and don't create glare for oncoming drivers.
