FREE BICYCLE TAIL LIGHT AND REMOTE CONTROL  The MJ-908 is designed for mountain biking and off road riding but a tail light will allow you be seen on roads and urban streets. Wireless remote control can be strapped onto the bike handlebar and switching between working modes. When not in use, the remote causes the light to continuously draw small amounts of power from the battery pack, this process will drain a fully charged battery in 1-2 weeks. Therefore we recommend disconnecting the light from its battery after each ride.
