ISEYOU LED Rear Bike Tail Light [2 Packs], IP65 Waterproof & Drop Resistant Bike Rear Light, USB-C Rechargeable, Safety Warning Strobe for Cycling, 6 Light Modes Available

loads of different light settings, my only gripe is the actual back of the unit could do with a rubber strip to keep it planted exactly where you want it with no possibility of moving about, i just used a strip of old inner tube glued onto the back of the light unit and it's now solidly mounted, Just me being super fussy really, tbh these are the brightest rear lights i have come across and the battery life is just unbelievable.

I love these little bike lights. They arrived fully-charged and I haven’t had to re-charge yet, after a couple of weeks of occasional use. They’re nice and bright and have a few different lighting modes. Easy to attach and remove. Great value for money.

Great product for the price, bright & easily fitted

Really great on dark nights and charge quickly. They have multiple settings, very durable and good value for the price. Barely have to charge them.

Great value, easy to put on bike. Nice and bright lights

I bought these for the back of my wheelchair. They're very easy to attach and are very bright. I like that you can change the sequence from having the light turned on continuously or have different flashing settings.

Charged pretty quick, good value for money, takes a bit of stretching to connect together when wrapping around your frame but holds nice & steady. Very good amount of brightness so you can feel safe knowing vehicles behind can see you easily.

Good lights BUT !!!! 1 has stopped working after 4 months of use
