Mystery interior lights

[Jones]

I picked these up a while back and would like to find more. Anybody recognize them or know the application?
MFR is 6T922 (Moody Precision Supply)
NSN looks like it's 12342403 but a search just shows "Item cancelled without replacement".

that appears to be an interior light for a HMMWV winterization kit. It mounts to the back wall inside of a heavily insulated cover for carrying troops. NSN : 6220-01-323-0431
