I didn't realize that DJI go did not mirror those patterns. DJI go's mission feature is far less in options than Litchi, which I use exclusively. These light flashes are prbly just a "Feel good" indicator to let you see changes in operation. Aside from the drones main light flashes which should be universial stating the drones status: GPS, ATTI, low battery, ect. You've stated the visual patterns that Litchi generates. Home lock also produces steady yellow lighting when used. I'm usually involved with other things while flying so I rarely notice the lights except when the low battery "Scary red" or ATTI "you better do something now" loss of GPS occurs.
