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

The product works well. Runs for long hours too if proper charging habits & routine is maintained. The attachment is pretty easy to use too. Doesn't get loose while riding. The durability is good with respect to the cost of the product. Has multiple modes of lighting and has good visibility too.

Very nice ie built quality and bright lights good battery backup

Easy to install. Easy to recharge. Different light combinations. And works for 3-4 hrs non stop before needing a recharge through micro usb port.

Definitely recommend if it is needed.

Good but problem in button

Light is good,but it's supporting plastic is too flimsy,it breaks easily,in 3 days of use...it just broke of while riding itself..The design is very poor.

Good item

Not good. Poor battery life

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!

Ideal for us. Just bought another pair, 2yrs later, after one got pinched. These really hold their charge well (for around a month with everyday use during winter; for over 6 months unused). Simple too - on/off/ flashing. No silly settings, bright and small.

Very good, easy to fit and take off and charge. One gripe is there is no 'low battery' warning light when in use to tell you it will need charging soon. I was using it one night and realised it was switching itself off mid ride (dangerous!) I assumed the light that came on whilst it was charging would also double up as a low battery warning light but it doesn't.

You can probably buy brighter rear lights for daylight conditions, but otherwise these are exceptional value and work really well. The light is easily removed from the mount which is square so that the light itself can be vertical or horizontal. Also the mount angle can be adjust through about 120 degrees so that you can attach to an angled part of the frame and still have the light facing backwards. Not sure about battery life yet but used them for a week or so on slow flash mode and had no need to charge them yet. Bought another pair as a backup just because I've spent twice as much in the past on a single light that's been inferior :-)

Work fantastic in all weathers on my commute.Having pack of 2 means I have a spare for another bike or while one is charging.Nice & bright in all modes👍
