Using this Lezyne e - bike light is easy. First, make sure your e - bike is turned off. Then, use the included direct X - lock CNC fork mount to attach the light to your bike. Connect the long power cable to the motor of your e - bike. Once installed, turn on your e - bike, and the light should come on. The intelligent auto day dim mode will adjust the light's brightness based on the time of day. When it comes to maintenance, keep the light clean by wiping it with a soft, dry cloth regularly. Avoid using abrasive materials that could scratch the lens. If you notice any issues with the light, such as reduced brightness or intermittent operation, check the connections first. If the problem persists, it's a good idea to consult a professional. Remember, the Direct X - Lock Mounting System isn't compatible with all stems, so always refer to the installation manual. For installation, as the light needs to be connected to the motor and battery, it may involve some disassembly of your bike. It's highly recommended to have a trained e - bike professional handle the installation to ensure everything is done correctly and safely.
