I did a test on the different modes.
4 lane road, no shoulder with curbs.
Speed limit 45 mph.
I ride at 15 mph. I ride this road 12 times a week.
The Five Strobe Flash with Pause, causes traffic
to move Left Sooner and Further away from the bike.
Run Time 6.0 hours.
The One Second Flash works with less effect. Traffic moves over later and not as far.
Run time 12.0 hours.
