Ça fait de la lumière!! La nuit ça éclair assez bien à l'avant et on est vu de l'arrière. La recharge usb est super pratique et l'autonomie est suffisante.

À bientôt en magasin !

Good light easy to fit for a good price
Front light broke on first use. Front section fell off, and bulb fell out. Waste of money! Back light fine for the time being!
Charge don't last more than one use. And takes ages to charge up.
I've had to return two of this same model now, it seems the switch button mechanism is built to break. Lasts 3 months, tops.
Quick delivery, easy to install, works as expected! Great!!
Light is bright.
Lights are bright. No blinking mode. Batteries are realllyyyy bad. Had to charge these twice in one outing with my powerbank. DO NOT GET THESE. Other models from Decathlon work way better.

The front white light does not blink. However, the rear red one blinks. Require USB charging. Untested the duration of each complete charge as I have just started using.
Couldn't last more than 2hrs. No blinking function. Not bright enough for night riding. Partly my fault for not reading enough for this product before purchasing it.
Hi Rukhaizat,
Thanks for your feedback about the ST 540 USB lights set. I'm sorry to hear that it did not meet your expectations in use. It should certainly last at least 2 hours for the front and 4 hours for the rear light. If you feel the product to be defective please reach out to our User Happiness Team to see about returning or exchanging it.
The reason these lights do not blink is due to EU (German STVZO) laws prohibiting blinking lights being used on public roads, as this model was designed with those road safety standards in mind. We've also made the information about the non-blinking lights clearer on our product page.
Once again, thanks for leaving a review and happy riding!
