MagicshineSEEMEE 200 Rechargeable Bike Tail Lights,200 Lumens Max Output,360° Visibility Bicycle Lights, Smart Brake Sensor IPX6 Waterproof Rear Bike Lights 5 Modes for Road Urban Cyclists

This is my favorite rear bike light by FAR. I've used the Knog lights, Bontrager, Planet bike lights, and a variety of cheap blinky lights.One of the main reasons is the secondary light which shines downward and illuminates the ground. It makes me feel more visible and I've noticed that cars give me more room. That might also be because this light is super bright. The battery is excellent and the smart brake light lights up when braking. All in all I just feel safer using this light.My other favorite feature is the seat rail mount which is super discreet and minimal. The light easily twists on and off for charging and is high enough on the bike that's it not obscured by my panniers. I've found other lights which incorporate rubber straps tend to brake over time and just don't look as nice.My only quibbles with the light would that it uses micro-usb rather than usb c but that is the same with all my bike lights. In my dream world these kind of lights would use wireless charging so they could be easily placed on a charging mat rather than fiddling with usb cables.All in all this is the best rear bike light I've used and surprisingly affordable considering all the features. I almost didn't buy this because I wanted to get a "fancy" rear light. I'm glad I chose this one.

As a light, this works great. The LEDs are very bright and are easy to see in daylight and darkness. The auto sensing feature seems to work well, blinking during the day and remaining solid at night.There are two areas that could be improved. One is the mounting system, which is basically a rubber strap that wraps around your seat post. It works fine for that position, but if you have a saddle bag or rear rack, you won't be able to mount the light on that. It would be great if MagicShine include clips for those use cases.My other grip with the light is that is has no reflective material on it, which means it can't double as a reflector when the battery dies.Edit: turns out you actually can attach the saddle mount to the end of a rack using zip ties. It would be nice if there was actual mounting hardware, but the zip ties work ok.

Amazing!

I love the light. It creates a nice halo of light on the ground around you. It is super bright to those approaching from the rear too. No way they are going to miss it. Charges using a micro plug and does so with ease.

I've bought a few cheaper other rear lights and this one surpasses all of them. Don't look right at it, after I was trying to figure out which setting I liked the best, I saw red spots for a while.

I didn't like that there was not a constant mode for the bottom and back light. If I wanted the back light to be constant, the bottom would strobe. My assumption is that it was for battery life reasons. Also, all the lighting options can be a bit overwhelming when operating this (too many options to cycle through). I ended up getting a simpler light.However, I did really like the tiny form factor of this, and the brightness was great.

Love it it very bright and really powerful.

The media could not be loaded.  Super Bright. Your like a floating Red Orb, ppl see you from far far away. The pictures and videos cant really capture how this light illuminates.
