I am a little uncomfortable with the flashing lights and the restrictions in motor vehicle statutes, although I realize that most of those refer specifically to motor vehicles. It's not so much the laws per se, but when I'm riding VC it seems like flashing lights may be misinforming drivers. Flashing headlight is in an ambiguous place legally and a red strobe just means something else. Flashing amber hazard lights may be the most appropriate for a slow moving bicycle but I've never seen that.
