Exterior night view NOT showing interior lighting

[TimSchrock]

A client wants a tall tower of their stairs and I want to show it light up at night time like a lighthouse, but my exterior camera, night shot isn't showing interior lights. 

I've turned off all other light sources than the one I want, Default lighting set selected, lumens cranked up to 10k, show in both ray trace and renderings, but nothing...

 

When I turn on the light source that is in the "Outside" room, I can see it thru the stair AND front door glass. When I turn on that light source and update the lighting, THAT light shows as "In Use" but nothing I can find turns on the added light source that is in the "Open Below" room (which is the staircase).

I found it. I can't use the Automatic light set. I switched to default go what I wanted
