lights in the aztekencalender

after the adventures, all lights in the first ring of the calender are burning, but does anybody knows, what´s up with the four symbols in the second circle? until now i have only the light for the manifold-bonus....
thanks for tips )

not sure what you are talking about for the "manifold-bonus" on el dorado. The second ring of lights I believe are only lights...

I think like caper, never seen any activity on these four fields or in the the center field. First i was wondering too, but there just decoration, sadly.
