USB Rechargeable bike lights Set-Super Bright Front LED Bicycle Light sets-Water Resistant Tail Light Easy to Fit & Mount-Built in Powerbank for charging devices

As bright as car headlights so it’s good enough for riding at night, my commute in the winter and through dark thunderstorms. I can’t say if it lights up to the indicated 300m to 500m but I wouldn’t be surprised. I’m sure other users would notice the light from that distance and beyond though. The strobe effect will attract more attention and prolong battery life too.Each light is a solid one-piece sealed unit as you don’t need to open it to insert batteries. On charging (via the micro USB port under the silicon dust plug) a red light indicates charging. This turns green when charged.Installation is easy. It comes with enough inserts (see photo) so that the front mount can fit most bike handlebars and frames. No tools required. Both can easily removed.I bought it because it is also a USB power pack and expected this to be bulky but am happy with the size. It’s about three times the size of the tiny light on my bike and considering its power-pack feature, it’s perfect for commuting. The front unit weighs 130g on its own and together with the rear unit and fitting bracket, the total weight is 225g. That might not suit lycra-clad enthusiasts shaving the odd gram off their ultra-light carbon road-bike accessories and aiming for the next PB on an uphill segment but it’s perfect for convenience, safety and all-purpose cycling trips, so it’s right up my street.
