1998 Toyota tacoma auto trans gear indicator light "D"

The truck will go into gear and drive fine just no green light. Is there a bulb for each one or is this a deeper problem? I can take apart the dash and get the cluster out but if not needed I'd like not to go that route. Any help or tips are appreciated.
