Compatible with MJ-902, MJ-906, MJ-908 bike light combos.
Uses CR-2025 battery to function, one comes with the remote.
Come with O-ring for handle bar mounting.
Must be paired before use.
NOTE: 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.
