Lumping several questions into two parts. I have an intense 360 degree Zenon strobe on the rear rack that is visible in all directions but for a narrow space at 12 o'clock. The 35 (at the moment) watt headlight is visible from 10 PM to 2 AM o'clock. Full coverage. On vehicles coming from the side I can either twitch the handlebars that way or even flex the rubber headlight mount. No problem with seeing the road surface with a broad beam. From the shadow of the front wheel tout to 50 yards or more I can see things. No videos, any volunteers? Every few months of night riding someone admires the rear strobe.
