Stereo & Electronics - What type of bulb is this?

I'm changing my dome light over to an LED type. The refence manual calls for a 214-2. Not sure what this bulb is supposed to look like. The replacement Festoon type 214-2 LED bulbs look completely different. The copper leads went through the loops of the bulb. There was no 'socket' that the bulbs fits into. I placed a 214-2 replacement bulb into place and bent the copper leads over to help hold it in place. If this is not a 214-2 bulb, what type of LED replacement bulb do I need to find? Can someone identify this bulb?

That's actually a #561 bulb rather than a 212-2 or 214-2. The 561 is a rigid loop bulb and the 21x-2 bulbs are end-cap designs. There are LED versions of the 561 available from several sites online.

Thanks for the info WhiteBird00, I found a seller on ebay that offers the bulb and in the color that I need.
