Well, it's difficult to get that on camera as it automatically adjusts exposure. So, by default modes are Hi->Lo->Strobe->Off. So, you're in Lo and road has opened up, there is no traffic, and you want to switch it to Hi. That means clicking three times, and going through Strobe and Off mode, which can be dangerous because you're fiddlig with light while riding and you're in the dark for a split second while you switch it on again.
Now it works like this:
-Single click: alternates between High (100%) and Low (30%)
-Double click: stobe mode, single click and you're back to whichever mode you were in
-Hold: switch off the light.
Now, my second light is on its way, and I plan to connect both of them to a single microcontroller. Also, one of them will have Wide Angle lens. So, basically, I'll have "low beam" (only wide angle on 30%) and "high beam" (both lights on 100%). Also, remote switch will be added to this contraption.
Standard light beam:
With Wide Angle lens mounted:
How my setup shoud work (alternating between Low and Hi):
