Ok, first of all... if anyone is looking at the silly stock "shift light" if that's what they call it, then you must have great eyes (better than mine which are 20/20). It is not very bright, and it is far more difficult to pick that up than a glance at a sweeping gauge which allows you to _anticipate_ the shift. If you wait til the light is on, then you're late on the shift.I prefer to be looking out the window rather than down at some gauge in an instrument panel. It seems to be a better place to be looking while banging gears at high speed.
Shiftlight set for 6000 for me. By the time I actually make the shift, its around 6200.
