Using the Lil' Cobber bike lights is super easy. To turn the light on or off, just give the single button a long press. A short press will let you cycle through the 4 pre - programmed lighting modes. When mounting, choose the right strap according to the diameter of your bike's bars, seat posts, tubes, or head tube profiles. The silicone straps are tool - less and removable, and there's also a magnetic mount for added convenience.
For charging, simply plug the integrated USB plug into a USB port. It'll take about 4 hours to fully charge. Keep an eye on the ring around the button. When it's red, it means the battery is low. Once it turns green and then goes off, your lights are ready to go.
As for maintenance, since the lights are 100% waterproof with an IP67 rating, you don't have to worry too much about water damage. But it's a good idea to clean them regularly with a soft, damp cloth to keep them looking good and functioning well. Also, avoid exposing the lights to extreme temperatures as this might affect the battery life and performance.
