If for any reason you wish to reset your ICON2 light, you can do so with the iOS app on an iPhone only. We plan to release this feature for Android at some point in the future.
You need to connect to the light in the See.Sense app, then select the light you wish to reset. Press and hold on the 'Forget this Light' option for 5 seconds and an option to reset the light will appear. You can confirm the light has been reset whenever the front indicator LEDs light up to show the current battery level.
