Anyone ID this? (1 Viewer)

Found a spring on the floor under the driver's side yesterday. Have no idea where it goes or it's use. Must have come out from under the dash, I think.
Does anyone know what it might be.
I did ID the lighter so don't need help with that.

Thanks in advance for reviewing.
