Vacuum balloon (Wikipedia link below excerpt)
First proposed by Italian monk Franceso de Lana in 1670, the vacuum balloon would be the ultimate expression of displacement lift power. A frequent topic of blue sky thinking, the basic principle has remained the same: A container strong enough to preserve a vacuum that displaces sufficient air to lift the container and an additional load. However, construction of a container strong enough to withstand atmospheric pressure while at the same time being lighter than the air it displaces is currently far from the realm of possibility given current technology[citation needed] (see unobtainium). Although this is perhaps an example of linear thinking: plasma windows could be used to contain a vacuum. Less exotically, magnetic fields could be used to keep the balloon from collapsing.

Notice the reference to plasma windows and magnetic fields
If, in fact, giant triangle shaped craft are a military platform, then the glowing lights might be plasma membranes used to control lift.

"It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it," McEuen told LiveScience.

Something I considered years ago was that hydrogen might be the lightest element due to a balloon like magnetic field that creates a vacuum.
H is almost undectable in space.
