- RAVEMEN TR150/TR250 Bike Tail Light, 280° Visible Bike Rear Light with Brake Detection and Auto On Off Feature, 3 Mounting Options

I haven't received any feedback yet from my cycling buddies as to whether the "brake detection" or "auto off" features work, but the light is easy to use, charges quickly, has several flashing modes, is very bright, and attaches very securely to my seat pack (which is important, since I've lost several other rear lights which fell off during a ride). Highly recommend, and IF the brake detection and auto-off features work as advertised, then I'll be even happier with my choice!

Works really good and has good visibility.

Great light, works as advertised. Have it on my gravel bike. Feel safer using it.

Finally a light that is not only bright from the back but also bright on sides!

Good rear light with multiple selections for lighting sequences/modes. Came with 3 mounting options, with easy twist on light unit. Light unit has a cross shaped connection that matches the mounting connection at 90 degrees then you insert and twist to secure light. That would all ways mount light in vertical position, being on the longer side. What did not work for me is the under saddle mount since I always have a bag mounted. I also could not mount it on my seat post due to the strap being too short, since I have a Richie carbon post that has a slight aero shape. So it will not work for seat post that are not a typical round. I managed to find a spot on the rear wheel triangle tube on the non drive side. Not what I had preferred but need a second light for night rides. I have it on full time mode with my other light on as a flashing mode. Satisfied with light brightness and modes but not the strap length. I also don’t use the clip since helmet doesn’t have a good mounting position and have lost one when I mounted it on my seat bag. Consider the mounting and brightness before purchasing. I would have purchased a brighter light if it would be my only rear light source.

This is the perfect tail light. It has multiple settings and the flash is quite brilliant. If you need a tail light this is the one you should buy

Very happy with this bike rear light and features. Nice feature with brake detection. Easy to charge and stays charged for couple of weeks with intermediate use. Hard to find a good light when you have a cargo carrier on the back fender. Most mount on the seat post

Really enjoy this tail light on my bike. This is probably the brightest light I’ve ever, my have also commented how bright it was. Grate purchase.

And it's quite bright.

Very bright 5 stars good quality .

Great light with excellent day light visibility on 250 lumen flash. Battery seems to last longer than the manuals 11 hours before recharge. During cycle tour several motorists let us know they were favourably impressed with the visibility the flasher provided.

Very good but the plastic is too thin and easy to break

Visibilité excellente. Il faut être un aveugle conducteur pour ne pas se faire remarquer.
