Occasionally, I encounter lights that I've come to realize are related to another aircraft, but they are in the wrong place in the sky and have their own behavior in relation to head movement (as if they were not using the correct object-to-world transforms). I've also found that they only render to the left eye, when I do find them. Usually after 20+ minutes of play. I'm pretty sure this is not a Superbug related issue, as I saw this issue before I had purchased the Superbug.
Today, I booted up the Superbug and loaded a previously saved scenario, and was presented with these lights right off the bat -- AND, I think that this time, they're from my own aircraft so I got to really examine them closely.
Here's a screenshot of what I'm seeing (top-left image is the left eye, top-right is the right eye, and bottom image is FSX itself):
