Review on 2022 Newest Powerful Bike Lights Front and Back, 7000 Lumens USB Rechargeable LED Waterproof Bicycle Headlight, Up to 18+ Hour Runtime, 16 Mode Bike Light Taillight for Road & Mountain Cycling by Victor Ceja

7000 lumens-black1 Like others we tried moving the mount back and forth between bikes and the mount broke in half. Everything was fine until I started fiddling with it and tightening it up again! The light itself is amazingly bright, illuminating an entire two-lane bike lane, oncoming cyclists might not be as grateful if you don't tilt it down, but it's great for your line of sight. This is now our favorite dog running light. White light for crossing intersections or landing, for main trail we only use red mode. Don't worry about running out of battery, drive 1 hour, walk the dogs for 2 weeks, and then we'll actively charge to be safe. Seller was very quick to respond when we complained about broken fasteners, just had to wait for them to be in stock before getting a replacement. Bought 2 more for our other bikes so we don't have to move the mounts back and forth again.
