It certainly is You can use the EMS's gear dependent shift light functionality and use this as the output. Just make sure you set the 0 column in the table to a really high number (25500) otherwise the light will get annoying when the car is moving slowly or between shifts. If you have rear gears you'll also need to modify the gear calibration.

I have not had time to recalculate the gear calibration yet

So little time to get things done
