Bike Tail Light USB Rechargeable-Super Bright LED Bicycle Rear Light with Red/Blue/Green Color Waterproof Taillight for Cycling Safety

The media could not be loaded.  I have 3I've had these for almost a yearto my Suprise they held up very well to outside conditionsI use them on my boat, and on my bicyclesthey last for a long time 6hours or more. never ran out on me so i dont really know how long they stay on.I did not take them off my boat last winter, they were exposed to extreme heat and cold. they still charge and work fine! hahahaI have alot of bike lights including the cygolite hotshot. this KEYWELL light does a good job. This light for me serves alot of purpose and can be mounted anywhere. unlike the hotshot where it looks best on my seatpost only. the KEYWELL light looks great when I have 2 on illuminating the ground or anywhere I'd like.Def. recommend the KEYWELL light . it has become my favorite "turn to" light for bikes and canoes.

Light is super bright and easy to use . Adds safety by increasing visibility

Pros: Well packaged, easy to install, multicolored light options. Cons: Light output is barely visible from the sides - contrary to what the pictures on the posting lead to believe. For what this light does there are better alternatives in the market. Will not purchase again.11/23 UPDATE — Weeks after my review, seller kindly contacted me to offer a refund. I thanked the seller as I had not requested one and the return period had passed. Seller expressed concern that I was not satistified with my purchase, and as a consequence chose to make their offer. I believe this speaks very well of the seller, who chose to stay behind their customer. Well done folks.

Waterproof, crash proof, bright, AND the battery lasts a long time surprisingly. I have two of these on my helmet for safety and they work great! I've ridden through rain and even crashed with them in, landing on one and giving it a small crack but it still works fine! For the price, compared to other lights, the function and convenience with the USB charging pit the lights over the top! Get them, they'll save your bacon!

Great product for the price

This is used on my bike as a tail light mounted on my back fork below my brake. I have a back luggage carrier that prevents a tail light from being seen if mounted on the seat post. The light is very visible with many color display options. I mainly use flashing red. The charge holds up for my rides which generally last for 2 to 3 hours.

Great price, bright, last a long time. Nothing to complain about.

It provides an ok light. There are brighter ones out there. Yet it is rechargeable

Only had it for a couple of weeks , now it doesn't hold charge anymore.
