Marc, thanks for the tips. I have a couple questions.

First, regarding flashing vs. non-flashing lights, my impression is that flashing lights are more attention-getting but are harder to localize. Also, flashing lights seem more prone to target-fixation (I think that's the right term) issues. Can you comment on this?

Also, thanks for listing what should be done, but you note at the beginning that much of what is posted here about visibility is wrong. Can you identify and debunk the common misperceptions?
