How will a single burned-out bulb affect the string of lights if each light is attached to its own wire?
When bulbs are connected in series to one another, a failure of one bulb will open the circuit and the remaining bulbs in the line will go out because they have no power. However, bulbs in the line preceding the failed bulb will continue to be lit because their source of power has not been interrupted. When bulbs are connected in parallel, a failure of one bulb will have no effect the remaining bulbs because the power is not routed through any single bulb alone.
