when I'm approaching a side road while traveling on the right side of a lane on a sunny day with speckled light and full tree cover ad deep shadows including hedges along the road, and there's a car coming from the side road looking for cars (not bikes) and likely doing a rolling stop (not a stop at all) I want the biggest brightest most alerting light on my bike. mine has saved me from being hit many many times because the cars see me and actually stop their car. while I admit looking ridiculous in open areas it's those few moments you need it unexpectedly that saves lives. in my opinion
