Second bike I have seen with some kind of small strobe light mounted low, left and right. They seem to flash alternately and not super-fast, but every 3 seconds or so. GREAT attention getter. I immediately noticed them in my rearview of my cage (this time it was at dusk with the dreaded blinding level California sun. Really a good safety item. Probably illegal, but I don't care. If you can get through the rush hour traffic and be seen...whatever. Anybody seen this or have any info? Thanks.
