Smart headlights would shine through the drops, lighting up the road, not the rain. Srinivasa Narasimhan, an engineer at Carnegie Mellon University, thinks he’s come up with a way to do it. Narasimhan’s concept is still in the very early phases, but the idea behind the technology is simple. Smart Headlights Will See Through the Rain - Popular Mechanics
