In double OO

I have two of them in flashing mode and the acts at night as the police :)
The notice even otherwise rather ge-mobile capte the common pedestrian-bike path-use bipeds from the front and from behind ... (because there what Blinkert how stupid and is reflected from any street signs).
The double blinkers then excited sometimes finally the desired attention of motorized and corresponding more considerate behavior ... the reason (irritation, better visibility, increased attention) I leave time to be seen ... but it works!
Have now in 3 winter months also annoyed 2 motorized oncoming had, who then in turn switched on 1x and 1x high beam headlight flasher ... but I'm happy to take into account the effect that I'll finally PERCEIVED in city traffic.
So better perceived by pedestrians on the way and need less ringing ... also better perceived by motorists in a double pack will remain lit also very good enough for dark lines (only one is a little low in the scatter range) ... I am fully satisfied and probierts of times as a double)
