Stop traffic with a tail light that’s actually smart enough to know when you’re slowing down! This 250-lumen powerhouse uses motion sensors to blast a warning to drivers the moment you hit the brakes. With a wide 280-degree glow and six flashy modes, you’ll stay visible from nearly a mile away while looking like a total pro. It even takes naps when you’re parked and wakes up the second you start pedaling.
