Smart Bike Tail Light Ultra Bright, Bike Light Rechargeable Auto On/Off, IPX6 Waterproof LED Bicycle Lights, High Intensity Rear Accessories Fits Any Road Bikes

Excellent

This light is amazing. It's built very well, with metal, and has a nice weight to it. The light screws onto its "base", which is zip tied to your seat mount. This is great because you just unscrew the light itself to charge it and then reattach, very easy. As of right now, I've used it for a total of about 4 hours and have left it outside without charging for 3 weeks. Still haven't had to charge it and it's going strong, and bright.The settings are really cool too, I'm impressed. The pulsating setting looks rad .. sexy, even .. and the accelerometer actually works! People are impressed by it. The braking feature still works when the light is on "manual" mode.As for mounting, yeah, like the title says, people need to stop whining. Just because zip ties are plastic and cheap and universal and found everywhere does not mean they suck. Would some fancy, custom-made mount be cool? Yeah, I guess. But do you really need it? No. Think about it, using zip ties ensures you always have a cheap remedy for a "mount failure" (haha) or if you want to upgrade your seat. Too lazy to go to the hardware store and pick up some zip ties or order them? Well, that's your personal problem. Stop being a lazy American. The zip ties hold the light PERFECTLY, no wiggle or anything whatsoever. They work. If it ain't broke, don't fix it.

This light fits under my saddle and it’s a perfect fit and it’s not blocked by my cargo bags. I needed a light that would mount to the saddle bars not the saddle stem because there was no room.

I've had this bike light for years. Kept it on a bike stored outside that I don't really ride anymore. Still works, though some of the light nacelles stopped working (not enough to negatively distort its "round" configuration). And because the charge port is protected, that part is in excellent condition. Now my wife uses it. Recommended if it's still available.

Great looking light when it was working. Only used it one day on my wife’s cruiser bike until it started flickering... Then continued to flicker... So on... So on...We tried charging it for a full charge cycle, restarting it, changing modes and every time we placed it back on the bike for a night cycle it would flicker relentlessly until manually switched off. I really wanted to like it and I hope some of the reviews aren’t actually fake reviews from bots cause maybe I just got a faulty one... I’ll try it a few more times but so far it might be a fail purchase. Time will tell.Update 4/18:After 1 week of use e light has been very inconsistent. I must say however, customer service has been nothing short of amazing! Very helpful and eager to make sure they are doing everything possible to make sure I am satisfied with the product. I’m going to give the product 5 stars from 2 from A+ customer service and a great product that I may have had just plain bad luck with. Would recommend them otherwise!

Small hides up under seat. Bright. Battery life pretty long. Value good. Mounting ok

I ride in NYC and this Light works perfect day or night. There a a lot of cyclist on the streets. I don't worry about Not being seen by other cyclist as well as most cars. I liked it so much I bought a second one and mounted it on my helmet. I set them on Auto- flash setting and when I break they both light up solid. In the sunlight the light stays off and only light when slowing down or stopping. Then at dusk the flashing light comes on automatically. I did deep research even watched reviews on YouTube, because riding in NYC I want to BE SEEN. Only Con is I with the Mounting system I like the way the light screws in the base Perfect, but the mounting system needs longer plastic ties or cut the wings and make it more like a flat button offering more mounting placement options.I recommend this light. Enjoy your Ride and Stay Safe.

great light, does what it claims however many say you can't use it with a standard seat/saddle bag. Yes, it's true most bags will obscure the light since it sets recessed under your bike seat. Since I already had a ROCKBROS Bike Saddle Bag, I decided to see how I could attach it directly to the bag but that was not possible..After thinking for a few minutes I looked at the bottle 'within' the bag and a light (pun intended :) went off in my head.. I decided to drill too tiny holes into a water bottle cap and ran a single zip tie through them. I needed to angle it 'up' due to the natural downward angle of the bag. After looking around my dirty garage bench I found a standard bracket with two holes in it and ran another zip tie through it. The results are below in the pics. Take care-
