Schoolyard Bicycle Tail Light with Brake Sensor: Brake sensor technology
Available Options
Imagine a tiny lighthouse for your bike, but smarter. The Bicycle Tail Light with Brake Sensor isn't just another blinky accessory—it's a cyclist's guardian angel after dark. This clever gadget does double duty: shining bright to keep you seen, then flashing even brighter when you hit the brakes. It's like having a built-in 'watch out' sign for distracted drivers tailing you.
Rain or shine, this little beast won't quit. Its waterproof guts laugh off downpours, making it a trusty sidekick for road warriors and dirt trail conquerors alike. And forget fumbling with AAAs—the USB rechargeable battery is a nod to both convenience and the planet. Slap it on your seatpost with the saddle mount (no tools, no fuss), and it clings on like a limpet, even when the going gets gnarly. City streets or mountain paths, this light's one job is to make sure you get home in one piece.

i got this for my bike rides around the neighborhood to keep safe with traffic and it does its job well making me more visible especially at night the way it mounts is simple and holds on even on bumpy roads which is good since i dont like fussing with things charging it is convenient no need for batteries but the sensitivity is a bit off it flashes when i dont mean to brake fully which might confuse drivers behind me compared to others in the same price range its decent but not the best value as it seemed to me overall it helps but could be improved
- Pros: the light shines really bright and gets even brighter when i slow down which is great for safety it stays on tight without any tools and charges easily with a cable one thing i liked is it works in the rain no problem
- Cons: one thing bugged me it seemed too sensitive sometimes flashing when i just tap the brakes not really stopping and for the price i expected a bit more maybe a longer battery life or something
