As already mentioned, take a back up light.
I think I’ve told the story here before but weirdest solo night ride experience was hooning around a blind corner and finding a proper, old-school tramp (as in travelling gentleman) had set up camp in the middle of the trail. Squatting down cross-legged, little billy-can brewing on the fire and everything. Cue me slamming on brakes, missing him by about 3 inches , wishing him a hearty good evening and pootling on my way. I don’t know who was more scared, him or me. Perhaps I should have stayed for a cuppa.
