Winnerer Sun Smart Rear Bike Light: Auto on/off with vehicle detection
Ever been caught in the rain, wishing your bike light could just handle it? Meet the Smart Rear Bike Light—your new best friend on two wheels. It's not just about being seen; it's about being seen without lifting a finger (thanks to its genius auto on/off feature when cars approach). Plus, say goodbye to the battery hunt—this baby's USB rechargeable, and yeah, it laughs in the face of rain with its waterproof design.
Why you'll love it:
- It's got brains—automatically senses vehicles so you don't have to play with switches.
- Battery life that goes the distance, and charges just like your phone. Convenience? Check.
- Built like a tank (but looks nothing like one) to brave any weather you throw at it.
- So light and sleek, you'll forget it's there—until it saves your bacon, that is.
