The "Shift Light " as you call it would appear to be very much an item fitted to rally or race cars and to my knowledge there are no members heavily involved in such sports.
I would think you may have better success in contacting a forum dedicated to motor sports or even contact someone who actually participates in rallying or such.
As a matter iof interest did the "light" not come with fitting instructions - if not you could try doing a websearch for instructions
