This rechargeable tail light flashes 50 lumens of high visibility from both sides and the rear of your bike. That's 180° of visibility, and 14 times the light of any tail light powered by AA batteries.
Mounts to your frame or seat post without tools, or clips to your bag or panniers.
Charges with your micro-USB cell-phone charger (phones sold after 2010), or with a conventional USB. If you use a computer at work during the day, you can charge this up during the day for your ride home. (It's like getting your boss to buy your batteries. Shhh...)
To mount the Vis 180 to a large-diameter seat post or another larger tube, use the Light and Motion Vis 360 Front Strap / Vis 180 Long Strap.
The optional Light and Motion USB Charger allows you to recharge from an AC outlet.
Share your Vis 180 with another bike using the optional Vis 180 Spare Mount.
