3) This happened after take off at night in dark IMC. I heard the
alarm. I'm sure there would have been no way I'd have noticed a
sticker changing color while coordinating with ATC in dark IMC.

4) With the digital gauge I was able to quantify my problem. Without
it, I'm not sure what I would have done. I wouldn't have had any way
to determine the level of severity.
