I'm sorry, I hate to be negative, but if I was following you and you had the turn signal on and the brakes, I wouldn't have a clue of what your intentions were. It seems extremely dangerous to me, unless I'm missing something.
When you hit the brakes, If I'm looking at one or the other directional lights, I would think you were turning in that direction. Very confusing to someone following you.
I have Signal Dynamic brake light modulators on ALL my motorcycles. I wouldn't ride without them. But not on the directional lights. I don't even like the runn'n lights set on "high" with a Kisan Signal Minder..........Too confusing to pinhead, cell phone flapping, cage drivers...:-)
I hope I'm not upsetting you, but I feel I need to respond..............Be safe my friend....
