I do some of my commute on the minute man bike path, less than a mile with 3 street crossings. I run 2 minewt 100 minis, one on the bar and one on the helmet. Also a minewt mini 150 in blink mode , kinda bright. Had a ped yell at me, " lights too bright". I also encounter ninja walkers, ipod zombies and bikers with no lights or reflectors. So where is the balance? Generally the commute is pleasant with walkers and bikers doing their own thing properly. I would rather err on the side of too much rather than not enough light.
