The snow removal trucks did a study. In short, the strobe lights did not avoid the trucks from being rear ended. They discover that with a combination of steady and strobe they reduced the rear end accidents. The steady light gives the driver approaching from behind a better way to judge the closure rate than just strobes alone. I used strobes and steady both front and rear. I use 500 lumen dynamo on steady and a 450(night) 700 (day) (700 cygolite expillion) lumen blinking. On the rear 1.5 w dynamo steady and a Serfas, I think is a 6w, blinking on the rear.

I get notice and experience the same reaction from drivers like Joey and Steve. Double O
