I'm thinkin that with NVS, the lights are blue? Not sure, but it would
make sense. I know before NVS came out the formation lights were all
green, but this would overdrive and blind NVG's. Wouldn't changing the
lights to blue be part of the NVS mod, or do they just keep em turned
off?

I haven't seen them on recent planes, but it's not a hard modification
to make - just a different formula in the EL panels.
