Help with Older Chicago Airguide Compass

[waterlogged]

:?: I have an older Airguide compass with a black and white wire exiting the compass. If I were to guess I would say they would be for illuminating the compass for night time/low light use. Can anyone confirm this?? I have searched relentlessly on the internet for this information and I can't seem to find any info.

The other thing it might be but I seriously doubt it would be for an aoutpilot or GPS.

The wires are for the night light.

for sure , black to ground and white to what ever lite switch u want,

keep them twisted, this helps with compass deviation.
