Aluminum oxide is a pretty good insulator, and using aluminum for both
the bulb shell and the socket almost guarantees low current 12 volt
devices will have a short service life without some kind of mechanical
or chemical intervention.

Try some  No_Korode on the threads and terminals.

As another poster pointed out, you've got aluminum oxide forming,
which is a very good insulator.  There's another risk, which is
that an aluminum base and an aluminum socket can form an oxide
"weld" which can require so much force to break that the bulb can
sometimes break from the base first, leaving you with base+glass
shards stuck in the socket.  I use "Tri-flow" spray lubricant on
a paper towel to wipe down the base before I install the bulb.

I have found that spraying some penetrating oil (Kroil)  and waiting only a
minuet or so will free many of the 'stuck' bulbs .
