Congrat's on the "new" e32 & welcome to the board. The info for replacing the bulbs on the OBC is scattered all over the place, here's what I was able to put together:

I'm thinking I saved this removal jpeg from Rainman" or "Bill R.", I forget which (maybe they're actually the same person, like Clark Kent & Superman?)

None of the links say anything about disconnecting the battery, but I would do so just in case (it's under the rear seat), have your 5-digit radio code handy.

This discusses removal & backlights:

This gives BMW part numbers for dealer bulbs:

This describes how to replace the bulbs:
