If they are the black plastic ones with knurled edge, they are subject, with
time, to developing semi-circular cracks in the top surface which are
somewhat difficult to see. These cracks will open up enough to leak fluids
(and sometimes light!) when forced onto the can.  Could this be it?

I throw away lids that are more than a few years old on general principles
and restock new ones (fairly cheap) from B&H.
