Map Courtesy Lamp Console 2005 MGM Green Lights?
 

I have a 2005 MGM with a moon roof. On the overhead "console", right in front of the two map light switches are two "slits" when the headlights are on, these slits glow green. What is their purpose?. Can't find anything about them in the owner's manual. Could it have something to do with the Homelink system?
