I've been trying to figure out if airplanes or helicopters ever fly at night with only white Nav Lights.

$\begingroup$ I'm so sorry! I've been trying to figure out if airplanes or helicopters ever fly at night with only white Nav Lights. That's the crux of my inquiry and in the course of google searching to answer my Q, I fell upon this website. Again, very sorry if this is the wrong forum. I'll take a look at the "tour." $\endgroup$ – Maria Elena Jul 28 '19 at 22:34

$\begingroup$ Shaky camera work, limited resolution, in the dark. I assume you're intending to focus on the flickering lights to right of centre, which could be anything. Whichever answer you get to your posted question ('yes' or 'no') I don't see how that will provide any useful information. $\endgroup$ – CatchAsCatchCan Jul 29 '19 at 2:53

There are no such things as white navigation lights - nav light, by definition, are red/green/white.
However, we're talking about filming lights at night. And the problem here is that the light source, no matter what colour, is a concentrated source of light in major contrast to the lack of light around it. And so the light will often 'burn in' on a camera and appear to be a lot of light, ie white, where the human eye will pick up the colours.
