On Longitude and CJ4, the spare barometer in the middle is super bright in the night, I can’t find any adjustment dial, is it dimmable at all? Thanks.
I agree…it is very bright (especially on the Longitude)
I looked around on both aircraft and couldn’t find and knob to dim them. However, there were knobs very close to the barometers that were marked as “Inoperative”
So, I don’t think they are dimmable.

I believe on the CJ, the center rotary dimmer switch (at the top of the panel with the exterior lights/Pass Lights/etc) controls the intensity of the backup altimeter.

This knob is for dimming the panel backlight, not for the backup altimeter (thanks for correcting me).
