Jeep Repair: instrument lighting, jeep grand cherokee, instrument cluster

Question
Hello Kevin,
I have a 2000 Jeep Grand Cherokee. The lamps behind my Fuel, Amp and Tachometer have finally all burnt out (they have going out one at a time for a while), now it is really dark on the left side. What bulbs do I purchase before I tear into this project? Also, in reading your contributions, ii would appear to be a wise move to disconnect the battery prior to removal.
Thank you,
Gary
