Review on 🚴 4000 Lumens Super Bright Bike Lights - USB Rechargeable Front Light with Long-lasting Battery - 7+ Hours Riding Time - Five LEDs & Four Light Modes - Free Taillight - Fits All Bicycles by Brian Wersching

Both lights can be installed easily and without tools. It also means they're easy to steal but have quick release buckles for both, even if the main headlight is difficult to turn off. The main light is absurdly bright and thankfully has multiple power levels so you don't blind people. It heats up quickly at max power so I can't imagine it lasting very long at this level, but even the next lower level is still bright and not as warm. One of the coolest features is the ability to charge other USB devices like your taillight or even your phone. Haven't fully tested it to see how long it lasts at different power levels as I charge it frequently. Charges fast because it's a USBC connection. The taillight is a good balance of brightness, options, and functionality. 4 different lighting options, some stationary and some moving. All in all a great light set.
