Bike Tail Light Radar, CYCLAMI Smart Brake Warning Radar Detection 500m Monitoring Distance, Auto Light, Rear Taillight with Visual Alerts for Approaching Vehicles, USB Rechargeable, IPX6

I ordered this CYCLAMI Smart Brake Warning Radar and I really like it. It has many different light settings/patterns, and they are all very bright! I like that the light is rechargeable, and the light seems to go a pretty long time in between charges.I've had a couple of close calls with vehicles that didn't "notice me" in the bike lane. This tail light provides me with extra visibility as vehicles approach from behind, and I'm all for anything that increases my safety while riding.

It is the least expensive device of its kind, but after a month or two the battery life is so poor that it doesn't last thru a one-hour ride. And that's one on bike paths where it rarely flashes. A disappointment since I replaced two worn out Garmins with it. Would not buy again, but too late to return.

This CYCLAMI bike tail light with radar detection has significantly increased my confidence while cycling on busy roads. The radar technology accurately detects approaching vehicles from up to 500 meters away, providing visual alerts on the device and allowing me to anticipate potential hazards. The bright tail light enhances visibility, and the automatic brake warning function alerts drivers when I'm slowing down. It's a fantastic safety feature for any cyclist, especially those who frequently ride in traffic. While the battery life could be a bit longer, the peace of mind and added safety it provides make it a worthwhile investment.

It cycles through 7 different light patterns/options. The light seems pretty bright. I tried understanding the instructions regarding the radar options but they just didn't make any sense. I'll use it as a basic light. There are cheaper options for just that though. The mount is pretty solid and tight around my seat post. Comes with something to mount under your saddle as well but my bike bag is there so it doesn't work for me.

This bike light is very bright and it comes with multiple adapters to attach the light properly. The light has buttons to power on and cycle through the multiple modes which include a steady light and multiple flashing options. Even in a lit area, the lights are very bright and really present well to provide visibility. The rechargeable function is also a huge plus. I'd recommend this bike light if you are looking for something bright and attaches easily and is easily chargeable.

I bike commute, and this light has helped me feel much safer, both day and night. For one thing, it's brighter than just about anything else I've seen; for another, the radar detection really works! I have mine mounted to the saddle rails, and it's easy to take it out for charging.That's the one thing to realize. This light has a relatively good-sized battery, and because it's radar-activated, it isn't on all the time. BUT. That being said, it's not just the bright light that drains the battery, it's the microwave radar which IS on all the time. Consequently, if you stop and forget to turn the light off, it's still going to be pinging away and using up the battery. So you have to keep a close eye on the on/off switch and the battery status if you want to have the light when you need it.Definitely 5++ stars!

great battery life. works perfectly. easy to install.

I don't typically ride my bike at night, but there are times when I'm riding near dusk or in shady areas when I wished I had a nice tail light. This light certainly fits the bill! It's plenty bright and has several different flashing or strobe modes that make it even more noticeable to drivers approaching from the rear. Two different mounting brackets are included so it can easily be mounted either directly under the seat, or on a seat post.I was unable to test the radar function yet, as I will need someone else to drive behind me to see what it does. When I'm able to do so, I will try to update this review with an explanation of that feature also.
