What is this light?

[Vertex_Jeff]

I was under the dash today in my '66 Belvedere wagon replacing some gauge cluster bulbs. While under there, I noticed this little light hanging down near the ignition key / ash tray area. It wasnt attached to anything, just hanging in the breeze. Anyone recognize what it is for? The length of wire from the main harness is pretty short - so cant be far from its home now.

How about a ash tray light.

Aftermarket light, not factory.

I was just in my heater control switch today, that lamp looks very similar to the push button illumination lamp. Except my 65 Coronet is not a 66 Belvedere.
