Map lights in 2000 Ford Explorer?

I have a 2000 Ford Explorer XLT that I'm having a small issue with. There's a flat metal, maybe copper, piece that fits in between the light bulbs and light housing. The metal piece broke in half on both sides and now my map lights are not working. Where could I find a small piece of metal to fit it? I'm guessing it helps with the connection since it was working fine before it broke.

I know the description isn't that great but it is just a small, flat thin piece of metal (copper).

That piece of copper (the bulb end clip) is riveted in the light bulb housing, you will have to replace it now. Next time, pry the bulb out from the end of the bulb.
