what is this?

[GoMangoBoys]

As I start the process of reassembling the car, I foresee many posts with the title "What is this and where does it go?"
So, what is this and where does it go?
How do I get it apart to change the bulb that must be in there?  I don't want to break it by not knowing what I am doing.
Thanks.

Lights up the heater controls.

Yup..mounts inside on the bottom of your corner switch panel to flood light on the heater controls...Just twist and pull it apart...I wouldn't PULL on the wire itself....never ends up good

A couple of pics to show one installed....

This is on a standard dash (not Rallye).

The base metal part is a slight press fit into the mounting housing... probably a little corroded, so will take some finessing it out of the barrel... maybe a shot of WD-40 to help loosen it a bit...

drench it in WD40
