Me! (sorry, no photos). Front light has been a Dinotte 200L, currently an Exposure Joystick. Taillight has been a blinky, currently have a blinky & a clip on light (Exposure Flare?) that clips ontop of the Joystick and runs off the Joystic's battery. I've been advised by other riders that following me with just the blinky running is annoying but tolerable; the Flare creates the impression you are being assaulted by the Eye of Sauron; I'm usually asked to disconnect it (and it isn't needed in those circumstances anyway). No feedback from drivers other than my daughter's "Dad, your lights are really obnoxious".
