Good. Very bright rear light

Good very bright rear light. Have not used often enough to check battery life, but easy recharge with USB. Not sure about durability of the clip attachment, but it clips easily to the Decathlon panniers I bought at the same time.. The silicone stretch holder does not attach securely and I can't use it without the panniers.

Perfect little light

Surprisingly bright, multiple seatings and a couple of different ways to attach it to my bike makes this a highly versatile rear light (although can be used as a front light too).

the switch

the button should be razed on the unit so you dont have to mess about trying to turn it on. I have super glued a little bit of rubber on the switch to make it easy for me. I was tolled this was the best light in that price bracket by DECATHLON employee he was right. the light it a very bright for a rear light and dossals you if you are close and can be seen miles away. change the button then this would a very very good buy .overall 90 percent out of 100 happy .would have given 100 if it was not for the switch

Simply love it

Easy to use. Easy to charge. Great lighting brightness. Love the 5 different lights options (fix white bright. Fix white shadow. Flashing white. Fix red. Flashing red) and the 3 seconds press to switch it off. The system to atach is great and easy to do. I would love to have an option to have a permanent fix system that allows the light to be removed or plug instead of potential thief removing the fixing part too. I love clip to the helmet. My helmet had a fixation set on the helmet itself. Not sure the 3M Tape will be strong enough to keep the light to be placed and removed often. I lost one light already in 4 months that was still on the helmet while I was walking or the helmet hit something and the light went out. Really easy to loose it.

Just The Job!

When used on the front, this light seems to provide the right strength of brightness to get you noticed without being 'retina-burning' to other road users and pedestrians. With its metal front it seems to be well-made. I don't ride in the rain a lot so haven't tested the water resistance. That it can fit to other Decathlon light mounts is really handy - I've no issues at all with it coming loose - and moderate branding is a plus point to me. Only real downside I can think of is the 1-second hold to switch it off, which is longer than other lights I've used. I like it a lot and think it represents good value too.

Great light very bright.

Great light, pushes out a strong intense light. Excellent.

Sturdy & bright, may fall out of mount sometimes

It’s a really good pair of lights I use all the time, it is very light and I carry it around everywhere but it’s also super bright and slim, it has fallen out of the mount a few times but I have always picked it up until a few days ago when the back light fell off when mountain biking and I didn't notice so will have to buy a new rear one. They are identical so there aren’t separate front and backlights which are handy when putting them on in the dark. They have fallen off the mounts a few times but haven’t broken yet which is could as they are very sturdy, the mount it stretchy rubber which can probably fit onto most seat posts and handlebars and is very easy to put on and remove. Would highly recommend, just be careful if going offroad.


Clips on my boys helmet and is really bright. He loves it and I know he’s safer on his bike / scooter. Several functions all are really bright and lasts aged between charges. Well worth a purchase!!

Good Backup

Not as bright as I thought it would be! But good design, compact & a handy back-up.

Not weatherproof

This light is NOT waterproof/weatherproof. It claims to be resistant to spray. One ride after rain, not actually raining and the water spray from the road has killed the light! It now will not turn on. I do not recommend this unless you only want to use it in the dry...absolutely dry!

Bright light

Bright light and easy to charge.
