Stay safe on the road with this Rechargeable Saddle Mounted Rear Light! It is easy to mount and offers multiple flash modes too! This light is rechargeable which is practical since it can last you a long time. It already comes with a charging cable and some mounting accessories to set you up. There are two modes you can switch to manual or automatic. Both modes have break-sensing functions. The difference is that you have to use the switch to turn it on and off when on manual mode.
