Part ID Help, Cigarette lighter delete plug?

I found this while going through some of my Dad's stuff, he was a Mopar mechanic for 36 years. It look's like a mid to late 60's Delete plug of some kind, anyone know what it is?

Found some number's inside the plug, don't know if it will help but....1972836 and 1199301. Thank's.

According to Arizona Parts:

1972836 DUMMY PARK BRAKE LENS BEZEL 1963 P,D

Wow didn't expect that..Thank's for the info.
