How do I/Can I create light in Substance Painter?

Like sources of light such as a backburner on a fast car or spaceship.

If not, would be could to see some LIGHT - BASED paints implemented into substance painter. :D

You can't create lights, but you can add an Emissive channel, in the document settings window and paint emissive on this maps to create glowing elements. You will have to activate the post processes to see the glow.
