The Tammy kit has this great brake light that they tell you not to use, I'm assuming because it would be hard with kit pieces, it takes some work to pull it off.
There's an extra LED (red) on the wiring harness that if you leave the throttle trim in the down position, it lights up and stays on when the tank is stopped. When the headlight is on, it's on as well dimmed, then glows bright when the tank stops. It's really cool. It's much better than the Xion brake light which only flashes on when you stop, then goes off.
I took the fiber optics and made a copper and aluminum housing for it and it works brilliantly, but I'm not sure which piece was on the tank was the brake indicator. There are a bunch of angled pieces with lens covers (that's what I fabricated) but then there is one simple larger lens type thing on the right rear.
I've searched for a few hours, but can't find info on which is which.
Any ideas?
Here's sevoblast's photo of what the angled piece is, but since they are everywhere, I don't think it's a brake light:
