Charge does not last three hours

I am on my second of these lights, first fell off on a ride, but neither of them have been able to last the one hour return ride I have to work and back. Every night on my way home I lose my rear light in the last 10 minutes of my ride, which is when I need it the most. It's a shame as the size and strength of the light are perfect.

Small but effective

Just what you need for a 2 hours ride, the product is small, the LED light emits a bright red light that can be seen from 40-50 m,can be easily mounted.


Thank you again for the comment. We will take note of this also!

Have a good day! :)



Après un mois d'utilisation, il cesse de charger tout seul, avant que la batterie soit remplie (mais il clignote toujours!)

So small but bright. Better flashing.

Only used it once so far and had to charge it up, but assume charge when I got it was to show it works. Can be clipped to your clothes or fitted to a rubber strap to fit around the seat stem. Was a bit of a struggle to fit to strap and then to stretch the strap around the seat stem, but when fitted was secure. Give me a bit longer to test it out.

Super little blinker light

Light and small, comes with usb cable and rubber strap to hold it on bike. Has good build quality and does the job of highlighting your position on the road for around 2 hours per charge. Has a neat feature when you turn it off that blinks if you need to charge it.

Super blinker light for rear.

Super , only downside is that you need to put them on charge after every ride. They do the job of lighting you up with a simple but bright flash of red. They dont have any other light modes. The small red blinker light to tell you when to recharge them is a neat feature.

LED light for your helmet

What’s not to like, a bright light which we use on our helmets! It’s rechargeable, but as it’s LED we hardly ever need too. When we do it’s simply 2hrs and then we’re back out. We use it during the day and it’s bright enough to be seen, at night it’s fantastic. A great bit of reassurance when out and about! Would highly recommend!!

Good but very small

Good bright light which is more suitable for attaching to a helmet or bag than to be used on a bike. It charges quickly and holds charge well. I have used this on my mountain bike because I try to avoid roads but it's there if I need it. I wouldn't recommend it for a road bike though.
