VU Meter Bulb Replacement
Each VU meter is illuminated using a filament bulb mounted in a
clip behind the meter. The bulb is a long life type. If it needs to
be replaced proceed as follows:
Unplug the cables and remove the console cover as described
previously. Carefully unclip the old bulb. Press in the correct type
replacement bulb. Refit the cover.
It is best to replace both bulbs at the same time. This ensures that
they both maintain similar life.
