Bike light knows when you're riding, when you're braking, and how dark it is outside: "While it’s important for cyclists to run a set of lights when they’re riding after dark, using lights in the daytime also helps make them more visible to drivers. That said, the chances are pretty high that daytime cyclists could forget and leave their lights on when they finish their ride ... plus, they’d go through batteries a lot quicker. Estonian inventor Indrek Rebane has already got those things covered, with his Velodroom “smart” tail light."
