The numberplate lights on my e30 are not working. When I checked them, I
found that there is no power getting to the bulbs. The earth is good,
all fuses are ok, and the bulbs are good.

When I looked at the wiring diagram in the Haynes manual, the wires go
back to something called a "Bulb Controller", this in turn then connects
back to the "Bulb Check Controller". Now, I know what the bulb check
controller is, that is the thing with the led's above the rear view
mirror, bur, what is the "Bulb Controller"? Where is it located? Is this
likely to be the cause of my fault?

Any help appreciated.

First thing I'd check is the parking light circuit - this separates the
number plate lights from the other lights so only one tail one front each
side can be selected.
