If I was a betting man, I'd bet that is not the original configuration. It looks to me as though that dash was recovered in leather and some changes might have been made. I've never seen two red lights between the pods before, and the only other Euro Pushbutton interior I've seen photos of had only the rotary switch without the toggle.
Without seeing the console switches to see what might be missing, I could only guess. Perhaps a rear fog light? Or, perhaps the interior light if the fog light switch is where the courtesy light switch usually resides.
Who's car is it? The definitive way to know is see what happens when the switch is activated.
