Using your Knog Blinder 600 + Plus bike light set is a breeze. For the Blinder 600, attach it to your bike's handlebar using the tough mount, either over or under the bar. Press the button to cycle through the 6 pre - programmed light modes. You can use it in full brightness for maximum visibility or switch to Eco flash mode for longer runtime. When it's time to charge, use a USB - C charger (not included). The intelligent button LEDs will show you the battery level and charge status. For the Plus Rear light, you can either wear it or attach it to your bike. Charge it using the integrated USB - A connector. It's that simple! As for maintenance, since both lights are waterproof, you can easily clean them with water. But avoid using abrasive materials that might scratch the surface. Store them in a dry place when not in use to prolong their lifespan. And always keep an eye on the battery level to ensure they're ready for your next ride.
