I truly believe that less motorists pull out on me when running my bright white strobe up front during daylight hours. I can't be sure about the science of why this happens. Does the flashing catch their eye better? Does the signal from eye to brain get translated better? Does the eye see blinking and the brain see a potential cop or ambulance and react by freezing motorist actions?

If you flip the question, I think you will find the answer easier: "If I always run my bright flashing light up front, will fewer motorists notice me if I remove it? I give this question a resounding YES...fewer motorists will notice me without the light. It only takes one motorist to ruin your day, or your life. THAT is the one you want to notice you. Run the flasher.
