  • this is it! very bright, brake sensing , good longevity, well made, easy to mount, inexpensive
very bright, easy to install, long battery life, brake function works well. The best light i've used so far, and good value for the money and features. it's bright enough to be seen by day, and at night it is impossible to ignore. I get about 6 hours of constant-on mode (i like that it stays on like a running ight, then brightens when it senses decertation. The power saving function does turn off if you sit motionless at a stop. This rarely applies to me since i ride in heavy traffic in Philadelphia. My bike is never motionless or without vibration. Even if it did go into power-saving, mode, it's sensitive enough that reseating your foot on your pedals will trigger the light to turn on. I mounted it permanently with the provided hardware and it's secure, no worries. I can still remove it easily by unscrewing it, leaving the aluminum mount securely in place. considering all of the above, the size, in that it is easily mounted , and the design is minimalistic but effective, , this is a well-made and solid option for taillamp. what got it the fifth star was the price. hard to beat without spending a lot of money on an over-engineered light. This is more than adequate. well done, well made. get thiis. ... show more

  • Best brake light
I love this brake light. Very bright. Multiple ways to attach and convient to remove for recharging. Nice blinking options and the activation when braking is very reliable. I've had mine for years and just bought another one for my wife. If I needed another brake light, I wouldn't even consider anything else. ... show more

  • Great bike tail light
Works great, battery lasts for many rides. Bright enough for the daytime for extra visibility. Easy to install on the seat or the seat post. The auto on and off works as advertised.

  • Nice light
Had to change to a saddle mount light after not having an under-saddle bag after putting in a dropper post. Light works well, however it is motion activated. Any slight motion turns it on and it needs about 30 seconds of no motion to turn off. So if it is sitting on my desk charging, and I inadvertently touch it or a piece of paper brushes it, it turns on. An on/off switch would have been nice. ... show more

  • Great brake light!
Really cool little light! I removed the seat from my daughter's E-bike and had no trouble attaching the metal clamp to the back of the seat rails using the included Allen wrench. I set it to the quick flash pattern for good visibility, and it lights up really well during the daytime and nighttime. The flashing light quickly transitions to a brighter "brake" light when the unit senses the bike is slowing down. The auto off and auto on feature based on motion (or lack there-of) is a nice feature and gives peace of mind that I don't have to remind my daughter to turn it on when she is riding around the neighborhood. For this price point, I highly recommend this light! ... show more

  • Super bright auto shutoff brake light. My second.
It seems like all bike taillights say they are super bright, but this one really is. I had an older version of this light a few years ago and liked it, but they have increased the LED count and brightness even since then. The all metal construction is very durable and I love the auto on/off feature. The light screws into the mount so you do not have to take everything off to charge it when needed. Easy to mount on most bikes, but my particular bike has a carrier basket that can block seat-post lights and so required a little creativity. I definitely would buy this light again. ... show more

  • Brake function really works, nice little light.
I like the feature that turns it off automatically when stopped for more than a minute then turns on again when it senses motion.
