Well you all have failed my question. At least for the answer I was looking for.

If you are flying at night straight and level at 5000 feet AGL on a 090 heading and you see the nav lights of a co-altitude aircraft in the distance directly in front of you.. You see the red light on the left and the green light on the right. What does that tell you?

The only way you can see both the red and green wing tip nav lights is if the distant aircraft is flying toward you or at a slight angle. If you see a red light on the left and a green light on the right, there is two possibilities. Either you or the distant aircraft is inverted.

The proper visual for an oncoming aircraft would be to see the green light on the left and the red light on the right.
