It sounds like I've already done much of what is suggested here just by using intuition. I got the vest, reflective ankle bands along with front and rear lights.
I am certainly convinced that cities could improve safety for everyone if they adopted some form of light pollution controls. Just think if they placed a shroud over every street light so that from a distance you would not see the light bulb - only the objects the street light was illuminating. It would be that many fewer points of light to distiguish as cars, bikes, or street lights.
