Just replaced the interior (courtesy) lights on mine - took <15 minutes all in ... and that included having to removed the cluster assembly (because I was pushing with a screwdriver in the wrong place so one of the holders popped out) ??
But as I had the cluster assembly off, I took a photo of the back it ... so those wondering what it looks like on an SE SR ...

PS - removing the cluster assembly was very easy; open the glasses pocket, remove 2 screws, and gently pull down so that the metal spring clips clear the headlining. Then push forward slightly so the plastic retainer tags clear the headlining. And with the cluster assembly off I could easily just press on the back of the lamp holders to stop them popping out again.
