Features: Some of the most important pieces of riding equipment are the ones that keep you safe. Increase both your visibility and your safety with Olight's BS 100 LED bike taillight. At only 1.7 oz, this little light produces 100 lumens, and has 5 different modes. A visibility angle of 260 degrees and 13 meters of max throw allows you to be seen easier in low light conditions. In a hurry? The BS 100 fully charges within 40 minutes, so you can quickly get back to riding. For more jobs that require some lumens, check out our flashlights. Mode: Output / Runtime
