Like Nut_N_Much said, the amber strip of the assembly is a bit buggy. I tried it out on my own Z to make sure everything worked and the amber was the only light lighting up with the turn signal. and this was with an LED turn signal bulb. When I put in the factory bulb, the flashing was not synchronized.
So as a way around it, I told my friend I would only leave the white strip wired in and leave the amber alone.
Unless we hear something new from the company, I wouldn't trust the amber just yet.
But I really like the way these turned out. I am tempted to try the same on my Z but I have a whole big project for my own that will involve some "reshaping" of the housing with some nice 3D printing involved
