Cadillac, Lexus, and at least one motorhome builder have offered night vision, but at Pentagon-like prices ($1750 to $6860) it has not been a huge seller--yet. The Lexus system uses near-infrared cameras, while Cadillac and others have a Raytheon-based system with refractive lenses to direct infrared energy at a receiver. Either method recognizes heat (from people, animals, or vehicles) and displays it as an image, before any headlamp could illuminate the object. Night vision for the masses is still in its infancy, but we anticipate more of it for use in inclement weather and to help avoid repair costs from collisions with deer or livestock.
