Why do we always have to "guess" at what drivers can or cannot see? I am a driver as well as a rider so I default to what I would find most visible. It's not rocket surgery.
Flashing rear, Flashing front.
I find the argument against flashing front always presumes the light is aimed at the drivers eyes. Mine is not. It is aimed down, so the light illuminates the ground directly ahead of me. This creates a large illuminated circle for drivers to see while at the same time not blinding them. assuming the light is pointed into drivers eyes is like assuming car headlights are always used on high beam. Occasionally someone does that but its not how they are used in general.
Bicycle lights are not the same as car lights. We don't have brake lights that intensify (well a few have fancy ones I suppose). We don't have turn signals and we don't have back up lights. That argument doesn't hold water. However, whenever a stationary or slow moving object or vehicle doesn't want to be hit it uses a flashing light. Construction barriers, snow plows, maintenance vehicles. Must be something to that.
Today, for the first time, I saw a rider on a dirt trail with a solid bright headlight aimed directly ahead - in my eyes. That WAS annoying, and a little odd, as it illuminated nothing but air.
