Installed my ST2 today, started the bike and while still sitting on the kickstand, the brake light flashes. Went for a ride as it was getting dark and my brake light flashes constantly. But it's not a consistent flash like 1,2, flash 1,2, flash.
It was like 1,2,3 flash flash, 1,2 flash flash flash, kind of jumping all over the place. Didn't matter whether I was accelerating or not. I'll look at it again on Saturday. Maybe try tilting it back so that it's less sensitive.

I adjusted the angle and that stopped the flashing when parked. But when it got dark and I went for a ride, the unit still flashed and didn't seem to come on when I slowed up. Today I'll switch the wires around. Because this comes from a foreign country, maybe the translation isn't correct.

Quick update, almost positive that I know what my problem is. For the Power wire I tapped into the rear Run light wire. My guess is that it doesn't supply enough current and I need to tap into a switched 12v line.
I was too busy to do that today, but will get to it on Monday and report back.

Received another email from ST2 support. He told me to try wiring it directly to a 12v source. If that doesn't work, they'll send me a new one.
I didn't tell him that I already tried that. But in the name of support I'll try it again.

Did you ever get this figured out? I will be installing the one on my wife's bike in the next couple of months.

what causes it to activate? Is it some kind of mercury switch that tells unit when slowing? Interested to know how it works exactly.
