1997 Olds Aurora Gear Shift Light

I have a 97 Aurora that the red line no longer works on the gear shift indicator in the center console. Is it a bulb that I can replace or a fuse?
Thanks

i also have this problem but the light only works in park it used to work in reverse too but it just recently stoped working so thats what i assumed it was i was going to takr it apart today but i could not figure out how to get the cover off if you can get it off let me know what you find out
