TOM make sure that your circuit is a parrallel one, not in series.Also you
cannot reduce the watt of the bulb because you will reduce the resistance
of
your circuit and let pass to much current on the same bulb (burning
action)

This is incorrect. If you reduce the wattage of the globe, the resistance
will INCREASE as it will draw LESS current at the same voltage to get the
lower power.
( Power = Voltage*Voltage/Resistance). As the bulbs progressively failed, it
is obvious that they must be in parallel as they would all go out if any one
failed in a series circuit.
