Gen 3 OEM shift light HELP

[bimmerm3]

There are three lights on dash that come on white , green and yellow. My question is which color is the main shift lite before redline ?

White is the main shift color. You can adjust it to say 10000 rpm where the max HP is at, and set the sub yellow and green lower at 8500 and 7000 rpm where max torque is.
