You don’t need a script to display a dual green/red or red/blue shiftlights,
1) open the Advanced panel,
2) set your SHIFTLIGHTS METHOD method to 2 (percentage)
3) double-click RPM THRESHOLD PERCENTAGE to see the sliders and just shift left all values and set blue led to zero

See the FAQ here to learn how to change RPM curve
