I just spent the past few weeks chasing a battery drain on the courtesy lamp circuit, so I was very interested to see your post. I also have these fancy chromed LMC lamp housings - two in fact, because it is a Suburban.

I don't know about yours, but neither of mine were conductive at all. The "chrome" is just cheesy plastic unable to carry any current at all.

They work just fine and ultimately were not the source of any of my problems.
