The most unusual aspect of a new headlight system being developed at DaimlerChrysler: Oncoming drivers can't see them. Well, sort of.

The system, recently demonstrated on a Jeep Grand Cherokee, combines conventional headlamps with invisible infrared lights. The result is a dramatically clearer picture of the road ahead.

It works like this: Two laser headlamps on the front of the vehicle illuminate the road with infrared light, then a digital camera records the reflected image. The image is projected in black and white to an LCD screen behind the instrument cluster.
