Bike helmet light

Awesome little light for the back of the helmet . Great price

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.

battery life not great

reasonably bright but not for long rides

Small light ,smaller running time

Didn't get two daily commutes out of it (18miles in total)between charging

icon-circle-checkmark Verified purchase

For the price, fantastic little light. Initially it looks too small to throw out much light, but it really does.

Good little lights

Really good for making sure your seen , Ideal for clipping onto a back pack or with the attachment which is included on to your bike , bright and last approximately 3 hours on a charge

Works well but not waterproof and needs a recharge every couple of hours

Handy light

This has a short life, around 2 hours, good while it lasts

Not water proof

Claims to be rain proof and have 3 hours battery life, mine has neither. After 2 weeks use, I have not got more than 90 minutes use before needing a charge and it now has water inside and won't turn off.

Thank you for your feedback regarding these lights. Indeed it seems that they have failed on both counts.
I have sent your comments on to the team who manages this item at b'Twin.
In the meantime, please don't hesitate to return them for a refund.
