If that's where Beacon is, then the lights must correspond to cities.

Actually maybe the lights do correspond to cities. When the narrrator was speaking, she said "even the most brilliant lights eventually flicker and die." Right as she says that, the camera goes into the streets of the city and shows Roman walking up. I think that shows the corruption in a city taking hold, thus the light is flickering and dying.
