Review on 🚲 Versatile 4-in-1 Bike Lights: Double Super Bright T6 Lamp, 4000mAh Rechargeable Battery, Extended 10 Hours Runtime | Perfect for Mountain, Road, Dirt & Trek Bikes | IPX4 Waterproof by Chris Wheeler

Great phone holder and super bright light for your bike. The battery life is incredible, and it also comes with a horn that clips into the cradle. It has a rail mount that can be easily disassembled. The horn is loud and easily plugs into the back of the battery compartment. The mount is very strong and the light is very bright with multiple modes. The only downside is the rear light as I don't know how it attaches to the whole device and if it's rechargeable. No highlighting instructions other than the shape.
