I run 20 reds every day here in columbia, sc. Never been ticketed, and they've seen me at least a few times. Pretty sure they just don't care.
One time I was stopped at a red waiting to turn left with my flashy LED headlight on, and a campus cop yelled something to me that I couldn't hear, I think that I wasn't supposed to be in the street or something. I ignored him, and he didn't say anything.
