Tail lights: Smart signals Quartz Obsession

You’ve seen the endless sea of red when you’re stuck in traffic. But chances are, you haven’t given the simple tail light much thought. Car designers past and present have, though — and so has Jason Torchinsky, co-founder of auto news blog The Autopian. These signals, which include the lights that indicate a car’s existence on the road, brake lights, and turn indicators, have traveled from oil lamp to bespoke brand signature over the years. All so we can show each other where we are and where we’re going. This episode is guaranteed to change how you think about any road-based journey (and it might involve a little tail light fan fiction, too).
