If you're looking for a bike tail light that's simple and intuitive, pick up the Olight BS-100! With its high output of 75 lumens in a 13-meter beam, this light is perfect for signaling your location to oncoming traffic and other cyclists at night. Its translucent housing expands the light's spill to create a bigger signal to other people on the road, enhancing your safety on the road.
Self-Adjusting Output
The BS-100's output can automatically adjust itself in specific situations. When you stop on your bike, the light will brighten to better signal your location. During the day, it will automatically switch to Smart Day flashing to be bright enough to be seen. It will do the same at night and switch to Smart Night flashing for clarity in the dark that won't blind drivers.
