Battery life isn't good
Used for 2 to 8 weeks
I am normally a big Decathlon fan..
I bought these without looking at the battery life..
2h & 4h.
I'm commuting 45min morning and evening.. I have to recharge every day..
I would not recommend buying this product. For such a bulky light battery life should be better.
V100 road 500front /rear led usb. Bike light set
Used for 2 to 8 weeks
So easy to fit to bike, no tools required, easy to recharge
500 series front and rear light set
Used for 2 to 8 weeks
Lights are bright enough. Very easy to get on and off. Inconspicuous so they are not a target for theives. However the front light seems to require a daily charge. Plus the wires supplied are to short. We don't all use a laptop to charge them.
Good Value Light Pack
Used for 2 to 8 weeks
These are a really good value set of front & rear lights. They are charged quickly (within an hour) via the supplied USB cable (nb: you will of course need a normal USB to main socket plug like the kind supplied with a mobile phone). They attach to the bike via a strong stretch rubber connector - so no fiddling around with screw connectors. The brightness of both lights are really good ...can't say how long the charge lasts as I've only used them for an hour at a time but this seems pretty good so far. Highly recommended..
