Volcano Eye Rear Bike Tail Light, Ultra Bright USB Rechargeable Cycling Brake Taillight, Waterproof Smart Bicycle Light, High Intensity LED Accessories Fits On Any Bikes, Helmet for Cycling Safety

Light, practical and extremely useful, this light is well worth purchasing. The “braking” setting (so following traffic can see the bike slow down suddenly) is particularly good. Battery life so far is decent - although I’ve not been cycling in the dark as we’re in the summer months, I’ve been putting the light on anyway as a safety device. All good so far. I ended up using the rubber seat post install rather than the one that installs to underneath the saddle - this was a bit fiddly. My only gripe.

This little light is excellent as does it’s job very well. It’s very compact and fits where ever needed and makes sure you’re seen. It’s only real drawback is that it does peddle the bike for you!

very happy with the light the only problem I had was fitting it to the stem as my bike has a small saddle bag under the seat so couldn't fit as per the instructions

Simple and discreet install. Easy to unscrew and recharge

Is a really good quality light with a powerful brightness
