Poorly Built

I used this light on my newly purchased OXELO TOWN 9 EF V2 ADULT SCOOTER. This has specific clipping points designed for these lights. I clipped them on, and on the first ride they fell off. I know for a fact that they were secured correctly. One I couldn't find and is lost. The other fell apart, the battery and circuit board were damaged.

Excellent lights

Grat value for money. Perfect lights for making sure you're seen - day or night. Great flexibility

avoid during the rain

first rain and already off

I'm sorry to hear there has been an issue with your bike lights. I assume there has been water ingress into the unit which is not normal. If you're not happy with these lights, please feel free to return it with your receipt for a refund or suitable replacement.

Many thanks


Great value

I love these bike lights. It's so handy to have both red and white LEDs on both lights. Easy to fit and remove from bike. I also like the clip, so I can tag it onto my backpack or coat if I am heading out in the dark. Brilliant quality and a bargain too.

Easy to clip, holds on nicely, long batery life, bright, can run in the heavy rain. Love it

small and compact

these are nice and bright giving good visibility, only issue is if they run flat you have to resort to another light as the batteries are self contained. For safety reasons i run with two rear lights in non flashing mode which means on long night rides you need to carry multiple sets.

Great price, brightness, reliability

Perfect lights for attaching to unusual places. Used two on my helmet while commuting for the last four years, both still work like new. Great viewing angle, great battery life.

Do NOT fit correctly OXELO TOWN 7 Scooter

Hey, I am an avid Decathlon shopper , being French I know the brand and products since I am a kid. Recently bought an Oxelo Town 7 EF, which btw is an excellent product. HOWEVER, I use it in the city and therefore need lights. The scooter is equipped to receive the Twin lamp, and clamp on the back and front. Well I am on my 3rd lamps purchases now(in nearly 3 months) because the rear one loose the clip at each bump of the road . So I disagree that the Oxelo Town 7 EF can receive the Btwin Lamp .And at this rate it is going to cost me more on lamp than the scooter it self.

I'm sorry to read that the lights comes off the rear mudguard. I suspect the fault may lie with the mudguard itself as it's curved not allowing the light to be held in place securely enough. I will ask the OXELO team to look into this matter.

A bit rubbish even at the low price point.

After about 12 weeks of daily use commuting, and overnight removal from the bike, both lights are completely filled up with condensation and look awful on the bike now. I would have thought being designed for use outdoors, that the waterproofing would be a little better than this to be honest. However, they're bright, tiny, and look good when they're new. Easy to recharge both at once with a double ended usb cable which is nice too.

Thank you for your comments regarding the condensation. I will forward this on to the product manger at Decathlon who is in charge of this item.

Not that good quality

I bought these lights a few months ago and I used them only a couple of times as I don't cycle during the night. Last time I try to used them I couldn't turn them on and when I tried to recharge the battery, it was showing that the battery is full. Since then I can not use them at all.

If these lights are faulty, please feel free to return them to store with your receipt for a refund or an exchange. It is odd that neither is working. The store will check them with you.
