Yes, at least one rear light should be steady when dark. As an approaching driver it can be hard to track a flashing light especially in the mix of other vehicle lights, it can appear to jump horizontally making it hard to tell if tracking on sidewalk, shoulder/bike lane or shared roadway. So I use a bright steady on post and flasher on helmet when dark.
