Two rules you're violating

1. Never use a single tail-light. You won't know when it goes out,
and it _will_ go out someday, no matter what kind it is.

2. Always use some steady light along with a flashing light, so that
the flashing light is perceived as having a coherent position in space.
It needn't be a bright steady light, but use something steady.

Except at twilight, I prefer two steady lights displaced horizontally,
their message being clearest then.

At twilight, I add a white strobe between them; they're not yet bright
enough to attract normal attention, but the bike is dark enough not
to be seen in tree shadows. Day-glow materials also do well at
twilight (there being lots of relative UV in the sky, on which they
work).
