I was watching Qualy on my DVR at Suzuka earlier, and GRO in the Lotus had one green light, and then red and blue, in succession, like this mod.
Here is the crazy part- after he was on the straight, he pressed a button, and 4 green lights stayed lit all the time.. then red and blue went up in succession like this mod.
Crazy stuff.. not sure what button he pressed, it was top left on wheel.. maybe 2nd or 3rd button from top. I wonder if the green lights were a reminder of which lap he was on, or some other notification system of some sort. I forgot to take a pic, or vid, and deleted the DVR file. it was in Q3 I believe.
