To be honest I haven't noticed any real adverse effect at night.. The one and only major night disadvantage was having your AI aircraft give the game away with their nav lights blaring away for every fighter to see for miles!.. Certainly can't say that cockpits give the game away..
What you can't control, even for online fighting at night, is what the other guy does with his monitor settings, now, that is the easiest way for anyone to get an advantage, regardless of what mods people are using!
