ROCKBROS WR05 Smart Brake Bicycle Taillight: Smart sensing technology detects braking to automatically activate brake light
For the urban commuter or weekend trail rider, this smart brake light transforms your bike into a safer, more responsive machine. While many lights focus on visibility, ours adds a layer of proactive safety with smart sensing technology. The light detects when you brake and instantly brightens, alerting drivers behind you a split-second faster than a standard light—giving you that extra margin on busy streets.
You get peace of mind with high-visibility LEDs that cut through dusk or fog, and a waterproof design that handles sudden rain without a hitch. It installs in seconds with no tools, so you can focus on the ride. With USB charging and long battery life, it’s ready whenever you are, making every journey more secure and connected.
