Bike Tail Light Rear Bike Light Rechargeable Bike Rear Light Waterproof Bike Taillight

Great value for money and does exactly what it's designed for.

Small yet the powerful.

Power last longer and working good.

I have Rock Bro. pedals I really like and was interested in this light when I was shopping for a new one. Hits all the marks with a variety of light animations and is rechargeable. The best part for me is attaching it to the seat rails, it puts the light up high enough so stuff on a rear rack or panniers don't block the light. Attaching the light to the seat mount feels pretty secure. Time will tell, I usually find a way to have them fall off or get smashed to pieces. YMMV.

Great light. Small and really bright, even for daytime riding. I ride for several hours a day and the light stays charged for days and days of riding. I ran an experiment and it stayed charged for over a week with a lot of riding time. Easy to mount. I have it on the back of my helmet. The elastic ring holds it secure to the helmet.

Quality is not too bad. Luminosity is good. But I was disappointed about the way to mount below the saddle. Other than that. I am happy.

It's bright enough, easy to use, a good mount (with 1 cavet), and battery life is average for the price point. The cavet: The seat rail mount leaves just a bit to be desired. It did not fit any of the 4 mtb seats that we have on hand without adjustment of the seat rearward to a non optimal riding position. If the arms of the mount were just a tad longer, or offered adjustability this would be a 5 start product. As it is I found a way to make it work by suspending the arms under the rails using zip ties (vs over the rail which would be more secure) but this is not optimal. I wouldn't doubt this will be addressed in a future iteration. Finally compared to my more expensive Olight taillight, I'd take the Olight over this even with the cost difference. That's a departure from my thinking regarding the Rockbros 1000 lumen headlight with solid mount vs my Olight 1000 lumen headlight in which the Rockbros wins out in that match. All in all, if you want a matching set and Rockbros is checking the boxes, I doubt you'd be disappointed with this taillight or the Rockbros headlight / taillight duo.
