Thank you for viewing. Everything in the photos is included. This is an excellent tail light that detects vehicles approaching from behind and displays the distance on the cycle computer. It was used for about a year, and the number of charge/discharge cycles is probably around 50. The seat post is aero-shaped, so it's thin and long. The rubber on the mount is starting to tear because it was wrapped tightly, but it's still usable. Some people seem to be using alternative mounts, so purchasing a separate one is also recommended. - Brand: bytron - Color: Red/Black - Type: Bicycle Light
