Nobody on this thread has claimed that lights or hi-vis do not increase visibility.
What I said is that I don't believe that lights during the daytime or blinking lights ever do anything to improve rider safety. There's no evidence one way or the other on either of those points so we have no choice but to agree to disagree.
