Ascher USB Rechargeable LED Bike Tail Lights 2 Pack, Bright Bicycle Cycling Rear Light, 4 Light Mode Options Safety Bike Light for Adults Kids Men Women Road Mountain(2 USB Cables Included)

The Ascher USB Rechargeable LED Bike Tail Light is an excellent addition to my cycling gear! I use one on the back of my helmet and another on the back of my bike, and they make a huge difference in visibility, especially in low-light conditions. The brightness is impressive, and the multiple lighting modes allow me to adjust for different riding situations. The lights are lightweight, easy to mount, and stay securely in place. I also love that they’re rechargeable, so I don’t have to worry about constantly replacing batteries. The battery life is great, and they charge quickly. If you’re looking for a reliable and bright tail light to enhance your safety on the road, I highly recommend the Ascher USB Rechargeable LED Bike Tail Light. They’re a great value and a must-have for any cyclist!

Which kind of early in the testing. It would be better if you were too ask me for reviews in a week or two. But so far, they are working great. One small problem. On a circular tube on a bicycle they sometimes tend to rotate a tad. Still working on that, but I’m sure I’ll figure it out. Very bright and that’s people know where I’m at when I’m on my bike.

Works exactly as expected. Four modes. Button cycles through each mode or solid or blinking. Bright enough. Easy to charge. Strong holder and easy to put on bike in different angles

Decent tail lights for a low price. Note that the long ones take USB-C but that the round ones are MicroUSB. This is not clear in the descriptions. I am trying to only buy USB-C but now I have 2 more MIcroUSB devices and will have to keep those cords around for while longer. PRO: cheap, good, can leave the strap on and just remove the light with the quick release, the long ones are USB-C CON: the round ones are MicroUSB

These lights are very bright in the dark and my kids love them on their bike! They’re not too big and honestly the right size. They also strobe four different settings and only one color red! They charge super easy and we’re thankful we got them for the kids!

This taillight is highly visible from a hundreds of feet/ Meters away. I like the rechargeable suction, and three light settings. Pretty cool items. It's bright!

Bright little lights, they recharge quickly last a while. They fit great, and they're easy to move around. Also like the shape of them

This product has multiple light modes and the brightness of the lights are plenty adequate enough to be visible during night rides. Unfortunately, the lights that I received had two fatal flaws they rendered each unusable: 1) reduced visability due to loose mounting mechanism and 2) disconnections due to road vibrations. The first light had a mounting strap that was loose. I would set the mount at an angle that would point the light straight back, but after a couple minutes of riding the mount would point the light straight down towards the road reducing rear visability. After a couple of days with this issue, I planned to switch out the two lights but when I went to unmount the first light I noticed that the light fell completely off the mount at some point during my ride. The second light had a much tighter mounting mechanism which gave me more confidence that it would hold its place. However, after about 100 miles of riding with this light, I noticed that the light would frequently turn off after a couple feet of riding. This was strange so I unmounted the light, turned it back on, and placed it on a counter undisturbed for a while and it stayed on with no issues. I then decided to shake the light to simulate moderate vibrations and that's when I heard something loose within the light housing and sure enough the light immediately switched off. I possibly could have gotten two poorly manufactured lights, but in my personal experience I would look elsewhere if your rides include less than ideal road surfaces. Also, if you receive lights with a loose mounting mechanism, return/replace them immediately for they will fall off at some point during your ride.

Mine broke after (reasonably for plastic) it smashed against the curb on the bottom of my longboard. That being said I cant help but feel there cant be more that can be done to make sure the 2 pieces of plastics that make the shell stay shut. Great lights just sad I broke one of mine after only under 2 months
