Some ambiguities about TR-3B

Why do you see TR-3B in some videos with all three corner lights, even though the angle is wrong, and if the aircraft is flying normally, you should only see the side view and not all three lights, as if you were standing right underneath it?

And why would a secret military aircraft have three extremely bright lights in every corner, what’s the point of those? The light in the middle, I could explain it with the anti-gravity core or something.
