Product review (5 stars): It's a light socket
The first of my two refrigerator lights went out a few years ago, and the second one started flickering recently.  As much as I enjoyed the dance party vibe, it was time to fix the problem.  It took about ten minutes to pop out the old sockets and pop these new ones in, and now I can see inside my fridge again.  These are OEM replacement parts, and they seem to work exactly as advertised.
