Ford is currently working on a new generation of headlights that will be able to show speed limits and other warnings to drivers on the road in front of them. At the moment, this kind of information is usually shown on a head-up display so that the driver can keep his eyes on the road.
Ford's tests are also underway on new lighting technologies that could take this to a new level. More may be accomplished with the car headlights than simply illuminating the road ahead. With this new technology, the driver can get important information without taking their eyes off the road.
