Well, no experimental evidence for adaptive funtion of flashing in
Noctiluca (and some species or populations don't even do it), but for
some other luminescent dinos there is good experimental evidence
supporting the grazer-deterrent hypothesis (Esaias and Curl, i think
1972, and White maybe 1978 or 79, I can find actual refs if interested):
Copepods (small, but with vision) grazed at substantially lower rates on
luminescent populations of dinos than on non-luminescent (dark phase)
populations of same species. Recent work by the likes of Busky and others
is clarifying the mechanism behind this.
Glow in good health...
