Defurhome LED Rear Bike Tail Light 2 Pack, Ultra Bright USB Rechargeable Bicycle Taillights, Waterproof Bike Back Light for Cycling Helmet Safety Warning Strobe, 4 Light Mode Options

Great lights, value for money, as described in the description. Nicely packaged and arrived next day. Easily mount to seat post and they adjust vertically so can aim the light more towards the ground or 90 degrees to the floor. Lots of flashing variations to suit battery life or solid light for night riding. Also very light if you wanted to carry a spare in your pocket for long winter rides

Good quality easy fit backlights with adjustable settings, good battery life easily last several days and are quickly recharged.

They work as expected, plenty of brightness and charging is nice and easy. If I had one gripe it's the lack of mounting options as it seems your only option are rubber bands, which isn't great when trying to attach securely to a pannier rack. On the upside I have a 3d printer and can cad the bits I need

I like this product. Good choice of light settings. Helps my child to be seen on her bike in the evenings. Especially in a poorly lit environment.

To be fair I was slightly nervous after reading the pile of negative reviews, although they are outweighed by the positives. But, the nights are drawing in and sending my dear lady wife out to earn a crust, it seemed a low cost investment.The lights arrived in really decent packaging and really looked the business. I charged them (see a comment later) and managed to fit one onto a helmet and the other onto a rear fork on the bike using the silicone strapes that they came with. Honestly, they seem to be really bright even in daylight.There's a selection of modes, ranging from solid, to 50%, to flashing and I'm able to see her cycling away from the front door for quite a distance. So, as the title says, it all seems fine to me.On the charging ... it's USB2. So you have to be careful to ensure that you put the plug in the right way round, and take care not to force things. Apologies for the mansplaining, but I only mention this because over the years I have trashed a number of expensive electronic items (tabloet, music player, camera) when the sockets disintegrated due to my being careless.But also, I would suggest you take a bit of care with the silicone USB seal and make sure thatr you don't rip it off as you reveal the socket; it's affixed to the light and doesn't come off, and also, when you replace the seal after charging, you really make sure that it sits nicely in situ.Would I buy these again? Absolutely, but since they are LEDs, I'm rather hoping that I won't need to!

Brilliant, just the job for mobility scooter

I don't use them as bike lights.

Phenomenal value. You could see them from France.
