Lezyne Femto Drive Rear Light
Lezyne Femto Drive Rear Light, Lezyne's Femto Drive Rear Light is designed to live quietly on your bike until its called into action by a quickly-sinking sun or a few wrong turns. It runs on a CR2032 watch battery and will run for up to 60 hours on flashing mode so a couple hour-long runs home in the twilight won't mean remembering to replace the battery.
