WOTOW Waterproof Bike Tail Light, USB Rechargeable LED Rear Bike Light with Long Runtime Up to 56 Hours, Ultra Bright 5 Mode Options Bicycle Safety Taillight for Cycling

Love this light. Had to get it because the one I had previously stopped working ( had the lazer lines for a moving bike lane). Anyway, the industry seems to be moving towards rechargeable instead of batteries, so I got on board. The functions on this thing are amazing. I choose one that had the longest life. I use it everyday for commuting. The strap has held up well, but I have only had it for 2 months. The charge on this last so long, I sometimes forget to recharge it. Get this light.

Bright. I would not buy again because no constant on mode, but rapid flashing mode comes close. Not a bad light, just my preference to have constant on.

0rdered and using this since last year, love it! Easy to attach anywhere on your bike or helmet, it has several light modes and I like them all and amazingly bright, people notice them from a distance even in bright sun, waterproof and recharge quickly. Just ordered another one to have a spare

Very bright light for its small size. Works great.

Used it a few times and it is bright and the battery has lasted 6 hours on the first charge, so far a great little light. Fast shipment and a great price, I would recommend.

Good value. Bright with decent flashing modes. Battery life is excellent. Haven't ridden in decent rain but the light is constantly covered in moisture and mud from sprinkler puddles and holding up well. Bit of a struggle getting the rubber clip to engage but doesn't look like it will easily fall off. Have literally charged it once in the few weeks of daily morning and night use on flashing mode.

I have 2 ebikes and got one for each. It provides excellent visibility to the rear of the bike. This is far superior to the factory provided rear light.

This little light of mine has been great so far! I’ve only had to charge it once since I got it and that’s even with riding upwards of 20 miles a day, the battery life is terrific! Visibility is awesome and provides me with a sense of safety as I know the light can be easily seen by cars behind me. Highly recommend!
