The Ship of Lights is the spacecraft used by the Beings of Light.
The Ship of Lights is an immensely large and fast spacecraft of unknown but highly advanced technology.
Viper pilots hear a strange piercing sound as it approaches. The craft has the ability to render people unconscious, as well as make them disappear (War of the Gods, Part I).
The "vanished" pilots and spacecraft are transported to a different dimension. When returned to their own dimension the warriors' memories have been erased regarding their abduction experience (TOS: "War of the Gods, Part II").
