yes, to summarize:
1. if lights are required, they shall be shown by night, during the day in restricted
visibility, and when deemed necessary (rule 20 read in its totality)
2. shapes (this appears to include flags) are for day use only
this has nothing to do with the alternative of using 3 lights and alpha flag if there's
not enough room in the vessel to use the other signals prescribed
(it does mean, however, that the lights will not be shown during the
day except during poor vis or if deemed necessary (talk about
an exception that swallows the rule), and that the flag will not be used during
the night)
