Smart Brake-Sensing Bike Tail Light — 100 Lumens, USB-C Rechargeable

Be seen the moment it matters. This smart tail light senses when you brake and flashes automatically to warn drivers and riders behind you — then switches itself on and off so you never ride unlit. With 16 LEDs pushing up to 100 lumens, you stay visible from 150 feet away in fog, rain, or full darkness.

• Brake-sensing technology — the light detects deceleration and flashes automatically when you brake, alerting traffic behind you without any input from you.
• 100-lumen output from 16 LEDs — bright enough to be seen from 150 ft away, even in foggy or rainy conditions or on unlit night roads.
• USB-C rechargeable — top up the built-in 800 mAh battery from a laptop or power bank; a full charge runs 17–35 hours in flashing mode.
• 3+1 lighting modes — cycle between steady with running light, a second running mode, and double flash + strobe with a simple 3-second button hold.
• IPX5 waterproof — sealed against rain and road spray, so wet-weather commutes are no problem.
• Tool-free mounting — straps to your seatpost in seconds, fits road, mountain, and kids' bikes plus e-bikes, scooters, strollers, and wheelchairs, and detaches instantly to double as an emergency flashlight.
