In Unity you can just use a emission texture, to get actual light you will add a light object to the scene.
In Maya again you add a emission texture. You can also add a blue sprite over the render and use a "add effect". Can also be done in post processing.
Easiest way to do it in Maya is just to add a bright blue light with some smeared blue billboards.
This is a easy to achieve effect with hundreds of ways to do it .
If you want I can upload a example for you, I know I am not good at explaining.
