Padonow Smart Bike Tail Light: Auto On/Off Flashing Lights Red Back Led Warning Flashlight Easy Mount Cycling Safety Brake Taillight USB Rechargeable Ultra Bright Light Sensing Bicycle Rear Light

This is a very nice tail light for your bike. It’s bright with many good flashing options. I really appreciate not having to recharge as often as other lights. Reaching is a breeze, just unscrew from the bike mount and plug into any universal C charger. The seat mount is so convenient I can reach back and turn it on while riding the bike. My new fav for all my bikes

I've been a bike commuter for the last eight years and that means riding rain or shine, day or night. As a result, I bought a lot of bicycle tail lights. This is one of, if not THE best tail lights I’ve ever owned. (I know some reviews have stated that the tail light is not bright enough during daytime use. Those reviewers need to look carefully at the instructions. The tail light brightness is controlled by a long press in the continuous mode.) It also seems to have some ability to sense ambient lighting conditions, and to modify the level of brightness, for example, when it gets dark decreasing from the maximum brightness level. I don’t think you would want to run this at the brightest setting in the dark on a group ride as you would blind riders behind you. At its brightest light is easily over 100 lm which is plenty bright. I just got it so I can’t say that I have evaluated if the run times are has advertised. That not withstanding, I would like to comment on the thoughtfulness of the design and the excellence of execution. The overall quality of this tail light is jewel-like. This appears to be a completely waterproof tail light with an IPX6 rating. It has very fast charging via USB-C, the three most useful modes, flash, strobe, and continuous, auto on- and auto-off, and an excellent and highly sensitive brake light I think that the included mounting hardware is extremely well done. I wish that more mounting options were available. If you run an under seat bag and have limited access to the seat post, it will be a challenge to mount this light. However, I was running an undeseat bag, and I like this light so much that I stuck my tools in my handlebar bag and I am running this with the saddle rail attachment. I feel very comfortable running this attached to my saddle rails, even though they are carbon fiber. The saddle rail clamp includes plastic liners which allow for clamp to be securely attached to the carbon rails without damaging them. In summary, I think this is a fantastic tail light. It would be fantastic at four times the price but at this price is it is a 100% no brainer! the best option for my money on the market.

Had a few different tail lights on my mountain bike over the years, gotta say this is my favorite. Most are plastic and don’t mount great, this one is metal, solid mounting option (including under the seat instead of an elastic strap, and that bracket is awesome. Super neat install, looks sweet mounted in that space since I have a dripper post, and works great. Having the brake light function is pretty cool on descents on the trails at nights too. I highly recommend this light.

I'll preface this review by saying that, for me, this is a 5 star product. I am very happy with the brightness, impressed with the battery life, and it was easy to install. I rated the product based on feedback I received from my riding buddies. Brightness - I gave it four stars because it is not as visible in the day as I was expecting, but it is plenty bright at night. Battery Life - I don't pay attention to manufacturer's claims about battery life. I have yet to use any product that holds a charge for as long as advertised. I was pleasantly surprised when I got about 20 hours out of it. That it about what I get out of my Wahoo so it's convenient to charge them both at the same time. Installation - I'm an engineer by trade so I don't have any difficulties with bike part installations. I will say that i checked several of my seats and only one spacer was needed for all (shimano pro, selle italia, specialized, prologo). You definitely will want to have a light or bright room when installing. I would recommend removing the seat for installation. I have had several of these "under the seat" lights. All the previous one used zip ties instead of screws. The machining quality of this light is unbelievable for the price. The all aluminum body and mount are secured on the seat rails by tightening the supplied machine screws. I recommend removing one side, insert the spacer, and then attach it to the seat rails. There is no need to remove both sides. It is a very solid mount. I will be purchasing a couple more for my other bikes.

Bicycle Real Back Light is what I need it Wireless And Rechargeable and water resistant for me I need it.

I have owned this product for over 5 years and it works without flaws. It is reliable and very visible. I am so pleased with this product that I just purchased another sample for my second bike. It has already been used in the dark and works very well. I recommend it.

I got a new E-bike and mounted this light under the seat. It's easy to use and charge. I like the features. Good product for the price!

I bought this product like 10 times for all my bikes and my friends bike, and I will keep buying this forever

The product works as advertised. I bought 2, for me and my wife. Good quality, sturdy, kind of heavy for the size (I think it is good), great bright and features. The USB-C works also well, complete charges did not take soo long. Also, for the rides that I usually do (commute - 2/3 hours) the battery never runs out. My friend was impressed in my first ride using it. I highly recommend it.

Excelente luz, súper fácil de poner, mucha duración, y sobre todo la función de encender por freno en forma automática y quedar apagada latente cuando no se usa

Does all it is supposed to do. I like the brake light. Much brighter then the other settings. Though I had hoped it would be brighter on the regular settings. On a over cast day it would be great. For the money, you really can't go wrong.

Me encanto el sensor que tiene para aumentar la luminosidad cuando frenas, muy visible por las noches, en el luz de día la luz del stop se ve bastante bien, siento que le falta un poco a la luz al no estar frenado en el dia

Very well made light not as bright as I thought it would be but I'm happy with it. The only thing I'm kind of disappointed in is the brake lighting it doesn't come on sometimes when braking and it comes on for no reason when you hit a bump even very small ones kind of annoying.
