Be seen when it matters most
Stay safe at any speed with this innovative back light that gets brighter when you hit the brakes. The lumasense uses an accelerometer to boosts brightness as your speed slows, alerting the traffic behind you. Powered by Chip-On-Board (COB) technology, its 30 lumen beam is housed in a compact, tough nylon case. Tool-free attachment quickly, easily and securely mounts your light wherever you need it - on your bike or helmet.
