towildTL05 Intelligent Rear Bike Light with Brake Sense Bike Taillight, USB-C Rechargeable Bicycle Back Tail Bike, IPX7 Waterproof 5 Light Modes Bike Rear Lights for Cycling Safety

Well built, good functions, weather proof and reliable. A little expensive but nice things aren't cheap and cheap things aren't nice.

I genuinely can't recommend this little rear light enough! Nice and visible and the auto braking feature is so useful. Great battery life and easy to remove to charge. I can't ask for better.

It needs a better fixing for a flat surface

Bought this as , having fitted a dropper post, I needed a rear light that would mount on the seat rails. The product does this really well and has many useful features. Would highly recommend.

It's VERY expensive compared to other similar bike lights, so I hoped the battery estimate is somewhat accurate. I bought it hoping the battery life is somewhat accurate ... it's not, it's nowhere near the advertised values. On a full charge, the rotation flash mode is advertised as 40h. I can confirm that it dies after less than 1 day.On top of that, the advertised auto turn off doesn't work at all. I was glad to not care whether I forget my bike lights on after my commute, but I can confirm that it never switches off. Every time I forgot it on, it stayed on for the entire night and was dead by next day (full charge).I tried two of them so far, bought at some distance apart, thinking I got a dud. They both behaved the same.It's not worth 26.99 GBP at all.

This light is great. It has different settings and the battery life is superb 👌🏾

Ok light in manual on and off, however auto sensing turns off while commuting.

Very easy to fit to sit post. It was supplied with both thick rubber bands, and zip ties (for attaching to the seat).It is very bright, with several different flashing patterns available. The brake light function works well.
