Which map is used for light?

So currently I’m making all the graphics for my game, with a predefined light source. But eventually, I’ll get rid of most of the shading, and just use a map, and an actual light source to create highlights and shadows on objects in real time. The thing is, I have no idea which map I’m supposed to actually use. I can’t remember which map does what, and I can’t find anything on the internet.

When I say “map” I mean like Normal Map, Diffuse Map, etc.

If I understand the question - I think you’ll find the answer under Rendering & Shading on this page.
