Trying to make a tron styled Skysphere and atmosphere

the images below are taken from tron and are almost perfect illustrations of the atmosphere i want to create, i’m looking for a midnight sky with lightning if its possible and could anyone give me some advice with regards to letting an Emissive light source act like light bulbs

This was just posted on another thread in the reply, about how to make emissive materials work as lights.

i can make the buildings and emmisive segments, im looking for the sky atmospere
