Yes, light bulbs can be powered by a parallel circuit.
The question is ambiguous, however one possibility is a parallel circuit, which would permit one light bulb to remain lit while the other light bulb was switched off. By contrast, if the light bulbs were connected in a series circuit, switching one light bulb off would cause both lights to go off.
In series
light up
nothing
That would be a parallel circuit.
then the other light bulbs in the circuit go out. However, in the case of modern Christmas tree lights in series, the bulbs are designed to short out when they blow, so that the other bulbs do not go out. They do get brighter, however, and this can lead to cascade failure, but that is why there is often a fuse in the plug.
For incandescent lights, they operate with a superheated filament. The filament slowly burns away and eventually breaks, opening the electrical circuit.
As they are connected in parallel (each has its own branch) the remaining bulbs keep shining exactly as they did before.
Parallel.
Its because it is in a parallel circuit and the dead bulb stops the power from continuing on to the other bulbs on the circuit.
