Police Strobe in my Dual Channel D3AA does not save brightness the way Bicycle Strobe does.
I do like that my Dual Channel D3AA with White and Red LEDs will use them for Police Strobe.
But Police Strobe brightness changes based on the last used output of the main LEDs..
Bicycle Strobe brightness is adjustable by ramping up or down in use, and it saves its last used brightness. It is not altered by the last used brightness of the main LEDs. I like this best.
I wish Police Strobe brightness worked the same way as Bicycle Strobe.
If Police Strobe brightness was not altered based on last used brightness of the main LEDs, I would use it when Im a Pedestrian in a crosswalk.
For my use as a Pedestrian in a crosswalk, I use Bicycle Strobe instead of Dual Channel Red and White Police Strobe, because Bicycle Strobe has memorized brightness.
