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.

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.

66-66 Plymouth B body has no heater controls lamp.

I know that. Just throwing out an observation.

Guys, I appreciate the responses. The orange wire feeding it sure makes it look factory. It appears to have a screw hole for mounting it somewhere, and when that housing is grounded, the light comes on with the dash lights. I will poke around in the ash tray area.......

See if it is wiring diagrams in FSM.

It goes with the heater control. Here's my 67 Satellite with a/c and the light package.
