ROCKBROS Bike Tail Light Rear Bike Light Rechargeable Bike Rear Light Waterproof Bike Taillightv

Update 9/24/2023This is a fantastic light especially for the price. I’ve used it a number of times and it’s a bright taillight.The claimed battery life is legit. I charged it up and put it in the red/blue flashing mode since that’s what I prefer. Shut off at around 40+- few hours. The set of four blue lights in the center are a battery life indicator and slowly “breathe” very 30 seconds or so.I love this because it means I can use the light all week if needed and I don’t have to worry about whether it’s going to shut off during my ride because I forgot to charge it.*****I only just bought it and I have yet to try it other than turning it on, playing with the settings, and mounting it on my seat post.After I first took it out of the box I plugged it in to charge it (USB-C). There are four small blue lights in the center and three of them were steady while one flashed. I assume that's the charge indicator. It wasn't long until all of the lights were off.I mounted it on the seat post with the large silicon band, the plastic mount, and the rubber cushion.Push and hold to turn it on and then push to cycle through the different patterns. Push and hold to turn it off. It seems bright enough. When it's first turned on it starts with the first pattern and doesn't keep a memory of the previous setting when turned off.I don't want it blindly bright. Just bright enough while flashing to help motorists realize there's someone near they might accidentally kill if they aren't paying attention. Appears to be more than bright enough for a rear light.I like the 40+ hour battery life claim! My previous tail light flashed but had maybe a couple of hours of battery life. I ride to/from work and when the weather gets worse (midwest cold, icy, and snowy) my rides get longer and if I forgot to recharge the light after a ride I risked the charge running out. I dropped and broke it the other day which put me in the hunt for something else.I like the price, the ROCKBROS brand, the feature set, and the battery life.I'll try and remember to update this review after I've used it for a few weeks.

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.

it's bright for its size. I like it that it has different interchanging blinking colors that will make it more noticeable. I also have a blinking light on the back of my helmet. so this light under my seat and additional light on the back of my helmet will me visible when i ride around my neighborhood at night.

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.

Flawless! Package came on time and item was exactly as described. My son loves his new light.

Plenty of colours and very visible. My bike's kind of old-fashioned so I was afraid I wouldn't be able to mount it on the seat (it has those spring-like seat supports). But the mount with zip ties worked just fine.

I just needed an out of the way bike light. I forget I even have this thing most of the time. It is very low profile. I have had it for at least a month now, use it every day, and the battery is still at %75.

Bright for a tail light because that is what it's designed to be. Some revues claim that it is not bright enough but It is not a front head lamp to brighten the road ahead. It is plenty bright for its intended use. As for the battery, I have used it for about 6 hours so far. The indicator says the battery still has 75% left. At 25% I will charge it again.
