I have an OTA King Controls system like this, factory installed, in my 2018 Navion. The video demonstrates the parts and functions. The little lights are on the roof mounted antenna directional control. Mine has little blue lights that indicate signal strength as I rotate the antenna. They are demoed at around the 7:30 mark of the video.
