Is the security light farther toward the front than the porch light is?

Yeah, so it's somewhat linear, I suppose.

But that would mean replacing some paneling...

I certainly don't look forward to the idea of moving switches to different places, especially on the first floor, given a lot of the wires come down the interior walls from between the floors. It's also why I've been too lazy to wire for a ceiling fan on the first floor. :-)
