JAPAN SPORTS Bicycle Rear Light with Smart Brake: Smart brake detection
Available Options
Why should cyclists care about a smarter taillight? Because getting seen is the first step to staying safe. This isn't just another blinky light—it's a rear light with a brain. It senses when you brake and instantly cranks up the brightness, flashing a clear 'hey, I'm stopping!' signal to drivers and fellow riders. That split-second warning could be what avoids a fender-bender or worse, whether you're dodging traffic downtown, grinding up a hill, or hitting muddy trails.
With 20 lighting modes, you can tweak it for any scenario. Need a solid beam for a dark path? Got it. Prefer a frantic strobe for rush hour chaos? That's in there too. Power comes via USB, so no more hunting for weird batteries—just plug it in like your phone. And with an IPX6 rating, it laughs off rainstorms and splashes. Installation is a snap on most bikes, and it's smart enough to turn itself on when you start moving and off when you stop, saving juice for when it counts. For daily riders, it's a no-brainer upgrade: reliable, intuitive, and built to keep you visible without the fuss.

Bicycle Rear Light with Smart Brake

why did i buy this so-so light well i wanted something smart for my bike rides with the dog but its extremely disappointing the brake sensing is nice but the rest is just okay most likely it will last a while but not sure i recommend it for others in newcastle its rainy here and it handles water fine but overall not great value
- Pros: it gets brighter when i brake which is good for safety and it has many light settings for different rides usb charging is convenient and it turns on and off by itself to save power
- Cons: the light modes are confusing to set up and it feels a bit flimsy not as durable as i hoped for the price and the automatic on off sometimes doesnt work right in slow traffic
