I'd like to be able to turn lights on and off manually for better visibility and for help spotting when I lose sight of my Mavic. When I first got the Mavic I was impressed by the bright white light in back, though I thought at the time it was a headlight. Is there a way to turn it on and off manually? Searching online for info can be futile as he information is usually out of date with changes in soft/firm ware. I did figure out how to set up the C1 button to turn on and off the front arm lights. To have similar control of other lights would be nice.
