There's no easy answer. I've many instances when cars would be stopped at stop signs waiting, then start just as I'm entering the intersection. This happens day or night, even when I think we've made eye contact. (no they weren't trying to get me, people are slow to make up their minds, so they wait through an opening and finally go when it's too late).

In a way I feel safer in the dark, because I can swing the H-bar sweeping my light onto cars waiting to enter, and this is much more obvious than depending on them seeing me in daylight.
