B body heater control panel question

What's the application of this heater control panel with light bar? I've had lots of 69 B bodies with light group but have never seen this light bar included. Was this from a 68 or maybe even from a C body?

I pulled one of those out of a '69 once - I think I sold it but I might still have it somewhere. It would have been a Belvedere or Satelite 'cause I never scavenged Dodges.

I have that exact setup in my 70 Road Runner non-A/C car (original)

The way I understand it is that the light bar is for '70's. I have had a string of '69's and I do try to add one, they work great.

70 B body for sure.
