I really want nothing that will distract a driver. During the day, I will run blinking red lights on the rear, along with my solid red light mounted on the rack. At night, all my lights are solid. I want to be seen, but I don't want a light that will make them fixate on me. People tend to fixate, and look at odd lights at night. You go where you are looking. In motorcycle riding, we call it target fixation. You look at a hazard, and fixate on it, and ride right into it. I don't want to give any reason for a car driver to fixate on me.
