Thomas,

 

I probably spent more time locating lights for the cabin than any other task on the plane.  I have attached photos of my overhead inserts.  The black eyeball lights are available from A/S and Lancair, the switches came from Radio Shack.  I still had to bend the tabs on the switches a little to keep them from hitting the roof.  The LED cabin lights are from West Marine, made by Hella.
