I am in the minimalist category. On the bar currently is just a front brake and some Lizard Skin bar tape. My night commute finds a Cygolite Metro 400 front light. And that is it. No cameras, no bells, no horns, no extra anything. I have my Garmin EDGE 810 mounted to the stem out of the way, and that is how I ride. I cannot stand extra clutter or unnecessary things on the bar or the bike for that matter. Having the rear light on there already bothers me but it is needed.
