Edward,
Have you checked the voltage reaching the fluorescent light?
Does this happen with engine running?
If the battery voltage falls below ~ 11.5V, this seems to be insufficient
for the inverter circuitry (that powers the bulb) to operate. Perhaps you may
have a battery problem rather than a light problem?

I have this with my Westy (replaced the standard 3-bulb unit with a fluoresecent
unit) due to 2nd battery not holding charge [it works fine when
the engine is running].
