WOTOW Waterproof USB Rechargeable Bike Tail Light, Ultra Bright Bicycle LED Taillight IPX5 Waterproof with 5 Modes Cycling Safety Rear Flashlight Long Runtime Up to 56 Hours for Road Bikes Helmets

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.

Wasn't expecting much out of these for the price came with a couple extra straps for monitoring charger cord and for how small they are there actually extremely bright. Only use them a couple times on flashing mode that's enough to give a little bit of light in the in full Darkness. And definitely bright enough to be seen from Cars.

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.

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.

This light is fantastic for the price point. The light is small in size but emits LED’s that are very bright red and can easily been seen from far away. Offers multiple light settings. Easy to install on bike seat post for a rear tail light. Waterproof is a nice touch to the overall design. Very happy with this purchase. Battery life lasts for hours!

Very bright light for its small size. Works great.

Easy to use. Holds charge a long time. Not blindingly bright. Simple attachment to handle bars. Would be nice if they had some other attachment methods. Seems watertight. Not very directional.

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
