I've noticed through the first two tutorials I've done that Point Lights begin entering the viewport with red x's on them. When I build those don't turn on. It seems to be implying some limit to the number of Point Lights in a given space. Is that space the lightmass importance volume, or a given scene? I checked the Point Light tutorial explanation to no avail.

You can only have 4 overlapping point lights. I guess your radii must overlap. You can read more about standard issues with lights in the lighting troubleshooting guide.
