Hello Flowmountain, the LED ring ALWAYS lights up, day and night, to indicate the reception status or operating status of the mower. What you can do, however, is activate a "night setting", then you have the option of having the LED light up "dimmed" or "extra dimmed" at night. You can't switch it off completely, but "extra" is already quite dark. You can access the menu in the app via Settings - Personalisation - Light settings. The sound can also be activated/deactivated here. In the operating instructions, the whole thing is described on pages 9 and 39, but the path has changed to the above. I hope I was able to help you, otherwise it's a great thing - "good mowing"! Greetings Wolfgang

You can also select eco mode, in which case the lights switch off automatically after 10 seconds in standby mode.

Hello Wolfgang, thank you very much for your quick and detailed reply. I'm already looking forward to implementing it this evening.
Have a nice week. Greetings Markus
