I had to replace a bulb and opted to do the upgrade to 9005 so I replaced both bulbs today after the quick and easy modification. When I went to remove the old bulbs, the copper ring that helps hold the bulbs in on the light fixture came out. I replaced it when the new bulbs went in but the rings aren't tight against the fixture and consequently, the bulbs are also not held in as tight as I thought it should.

Looking at RealOEM, I can't see this copper ring or a part number for it.

Any comments or suggestions?
