Not a bad product

Suddenly stopped working after 3 years

Decent-enough light while it was functional but it suddenly stopped working after 3 years.

Low battery

Low battery quickly and takes a bit of time to remove and install

Ok but not brilliant

It does the job and the light is powerful for cycling where there’s no street light. But would be better to flash also to be more noticeable to pedestrians and then also the battery would last longer between charges. I have an additional white light that flashes and use both of them at same time. No issues with charging it or the strap.

Complete junk

The USB charging port detached itself from the lamp and is now free inside the housing, the second time I wanted to charge the light. Utter garbage and disgrace of a product. They should never have sold this to anyone.


Bought this product 3weeks ago rubber snapped on strap rendering it useless waste of money lamp is bright though

Poor quality

Bought yesterday to replace a broken light fitting (and thus no way to mount my normal light) for my commute. Charged fully when I got home and fitted to bike this morning. Firstly, rubber strap will not fit all handlebars - this fitted at the narrow end but its position was too far left to light up the center of the road. Secondly, no flash mode. Very important for being seen by idiot drivers. Last, after 40 minutes of commute, the charge light started flashing red. By one hour the charge had failed. Promptly took back to store this evening for a full refund. I would not waste my time with this product.

Thank you for your detailed feedback regarding these lights. I have forwarded them all on to our design team at Decathlon Cycles.

Stopped working after a few months

Great when it worked, bought earlier this year, on a bike kept inside and charged regularly and properly , only used regularly in the last month, now red light shows charging went blue, and light now won’t work. Had to buy new light en route from a competitor. Not a great experience guys.

Thank you for posting a review of your lights. Please return them to us for a refund or an exchange.

Rechargeable lights

Bought two of these last summer while on hols in France. Have been using them all winter and worked fine until now. My commute is about 30 mins. Both front lights will not switch on even though they appear to be fully charged. This happened to both within two days of each other. Tha back light is still working fine.

Thank you for taking the time to give us feedback on this light.
I will forward your comments on to the product designer.
Please return them to us for a refund/exchange.

Not great for longer jorneys

Bought 2 weeks ago. Used every day. Full charge takes hours and then after 40 minutes the warning light comes on. Lasts about another hour after that. Its a good bright light though, with a good beam and good distance. If you are doing short commutes and can charge it in the office its ok. Doesn't flash either which is unusual these days.


Sorry to hear tht you are not happy with the 500 USB light, as the light is quite powerful this drains the battery quicker than the other lights that we have due to the small battery. The lifetime of 1 charge is 2 hours as you have mentioned, this is noted on the packaging and the website.

The light doesn't flash as the light is designed for countries such as Germany & France which have strict laws regarding the lights meaning that they have be to a minimum of 10 Lux and can not flash.

If you are unhappy with the product you can return this to your local store for exchange/refund with proof of purchase.

faulty product

33rd lights I got replaced. each time same story though. light become unusable after 3 rides. could be due to component unable to deal withvibration or battery life itself, very disappointed. back light is fine thought

Hello Oliver,

Thank you for your reviews on the 500 USB light. If you could reply to this e-mail for me in some more detail into why the light is now unuseable that would be great. I can then pass this information on to the product manager so that they are aware of this issue. Please do not refrain to return the light for an exchange or refund.
