Olight Red LED Tail Light I used this a few years ago when I was competing. The only accessories included are those shown in the photos. There are some scratches, but it works without any problems. - Brand: Olight - Model Name: RN 120 - Color: Red - Accessories: Mount, USB cable (Type B) - Mounting Type: Clamp-on It has a strong light output and various modes, making it very easy to use. Why not use it as a safety measure for your cycling?
