Smart Brake-Sensing Bicycle Tail Light

A rear bike light that automatically brightens the moment you brake.

• Brake-sensing auto brightness boost
• Up to 150-meter visibility range
• IPX-6 waterproof durable construction

Riding after dark or through busy intersections means trusting that the drivers behind you can actually see you in time. This rear bike light features a built-in brake sensor that detects sudden deceleration and automatically intensifies the beam, giving drivers behind you a clear visual cue when you slow down. The LED-COB lens pushes up to 100 lumens and is visible from up to 150 meters away. A 500 mAh rechargeable battery runs for 8 to 12 hours on a single charge, and the auto-shutoff kicks in after 4 minutes of no movement to preserve battery life. The IPX-6 waterproof rating and durable aluminum body mean it holds up through rain, gravel, and daily commutes. Mount it to your seat post, helmet strap, or backpack strap with the included clip, and you are ready to ride.

Brake-activated brightness
A built-in sensor detects sudden stops and automatically intensifies the light output. This gives drivers behind you a clear, immediate visual cue when you decelerate.

Long-lasting battery life
The 500 mAh rechargeable battery delivers 8 to 12 hours of operating time on a full 3-hour charge. A USB charging port makes it easy to top up at home, at the office, or on the go.

Visible from 150 meters
The LED-COB light source combined with a precision lens pushes output to 100 lumens and reaches drivers up to 150 meters away. Whether you are riding in twilight or full darkness, the beam cuts through low-visibility conditions.
