They are 80mm CDR's Sliver Diamond with two notches add to the center hole allowing the bulbs to fit thought. Depending on the placement of the CD Bottom Out or Top Out you will get two different reflections. One bottom out gives you a rainbow reflection or top out no rainbow reflection. But the real reason that they happen to be there is they are recorded with the DMC manual, my vin # and other information about the D. Yes I change them out once a year adding show photos and maintenance work etc. Hey there is no room for a 6" manual and photos any were else. Yes you need a screwdriver to get to them but I make 3 and keep one in the D. And I do not know how much of an increase of light is reflected through the lens.
