If they get dim it sounds like they're loosing power so possibly a loose connection but those things are huge and don't really "come loose". I would say the bulb but it being more than one that's out. Have you removed it and checked it out yet, there might be a simple wire grounding out somehow.

I dont see any sign of water. Just pulled the gauge cluster and reset all the connectors no change. I dont drive the truck much, i think i have put 1000 miles on it since 2010.
I had weak batteries and replaced them and and did some PM on the truck. New starter relay, battery cables, alt, belt. Could this be a GEM issue?

I'm going to try removing all the new battery cables and reclean connections. When i had the cluster out i checked everything out on the back of the panel no oxidation on any lamp sockets, ribbon cables, and all the resistors, jumpers and diodes and checked out. I noticed with the engine running my volts at the battery were only 12.6 seems a little low. I'm going to have the batteries tested today and try to pull the GEM and check for any signs of water damage or oxidation there. From all i can see thru the dash opening, the top of the GEM has a light layer of dust and no water staining.
