fwiw - I found adding a rear strobe to my left drop bar, (in addition to my light on my back rack),cut down on getting buzzed, aka close pass or someone cutting back in front of me too soon. having that strobe up front helped them gauge when it was safe to move back over & helped remind them I need some courtesy room while they are passing. I tried doign it a few diff. ways w/ a few diff. lights but wound up happy with this one, this way






on my way home last night, driving my car, I passed an electric bike. they have nice lights on the tips of the bars. red facing rear & white facing front, in addition to their front & rear lights. the lights on the bars were helpful to me as a driver as I was passing the rider
