The Femto USB Drive LED Rear Light from Lezyne is the perfect choice for commuters and recreational riders looking for a simple and inexpensive way to add visibility. This LED cycling taillight may be compact but it’s still able to offer over 180° of visibility thanks to its Wide-Angle Optics lens. It comes pre-set with a few output modes that create up to 5 lumens of light, enough to be seen on a road at night. When used in Flash mode Femto can run for up to 15 hours giving you hours of use before needing to recharge. That being said, recharging this light is a very easy task due to the Micro USB cable included and the USB port stays clean and sealed with a secure, threaded composite matrix cover. Other notable features include its durable co-moulded construction, IPX7 water resistance rating and versatile mounting strap that quickly mounts to a variety of post sizes.
