Carnegie Mellon scientists invent headlights that make rain, snow 'disappear'

The problem with driving in the rain at night is not that headlights aren't bright enough. They're actually too bright, the reflections off the raindrops momentarily blinding the driver. Some folks smarter than us at Carnegie Mellon have figured out a way to minimize the reflection effect using some pretty high-tech gear. They combined cameras and computers to predict the trajectory of each rain drop. That's impressive enough right there. But how does that help improve visibility in dark, rainy conditions?

"If you know where the rain drops are, you can sort of stream light between them," says lead researcher Srinivasa Narasimhan.
