This is inconsistent, and thus likely to lead to followup problems.
\transposition bes declares the relation between printed notes and
sounded notes to be c' to bes yet you use \transpose c bes to make the
relation between printed notes and sounded notes c' to c'.

Consequently, the quote is unusable. There are basically two fixes for
making trumpetNotes self-consistent: don't use \transposition, or don't
use \transpose. Of course you can also fix this by writing
\addQuote "trumpet" \transpose bes c \trumpetNotes
but that seems really backwards.
Once your quotes are internally consistent, you should find using them
reasonably straightforward. If you are using them in a passage for
transposing instrument, \transposition needs to be correct in that
passage in order to make sure that LilyPond knows how to convert
sounding pitch to printing pitch.
