It's been a while since I worked on that circuit, but that's how I remember it and that what I see in the diagram.
 
Edit: confirmed. Using the cig lighter as a constant source of 12V+ and ground, the courtesy lights definitely have a constant 12V+ and the ground is switched. |

I did the same test and got opposite results 

Here is a video I made. 
Sorry it's not very clear, but it was hard doing it with one hand holding the phone.

Just to give the full picture, this is 02 996, and I also repeated the same test with the test light connected directly to the battery.
