Using the Moon Light Comet - X Rear is easy. First, use the quick - release universal bracket to attach the light to your bike's handlebars. The bracket fits both round and AERO style bars. If you want to use it in other ways, you can also use the optional accessories like the rear rack mount bracket or saddle rail bracket. To turn on the light, just press the button. You can cycle through the 3 steady modes and 4 flashing modes. The mode memory function will remember the last mode you used. When the battery is low, the indicator will show it. Charge the light using the provided water - resistant USB cable. The automatic fully charged cut - off system will stop charging once it's full. For maintenance, keep the light clean and dry. Since it has IPX 4 water resistance, it can handle light splashes, but don't submerge it in water. If you need to adjust the mounting, use the 2 O - rings according to the diameter of your handlebars. And if you want to control the light from a distance, you can use the optional USB remote control.
