anyone have any experience with this little rotating LED beacon from Banggood?
Applying power runs the leds ok but the third wire does some form of mode selection but all the videos I've seen just show it connected it to a RC receiver and no details to use it separately
RTC
According to the first comment on this vid, it looks like you can control it via PWM, try connecting it to a PWM pin on your arduino and cycle thru the values to see if it responds.
But that's just an assumption based off the limited information I've found thus far.

Not PWM. Use the Servo library.
