If one bulb burns out, the rest will keep functioning. This makes it simple to pinpoint the problem bulb and replace it. The other feature that makes parallel wiring preferable for Christmas lights is that adding strings will not impact the brilliance of the lights on a whole. The amount of power flowing to each bulb remains constant.
The only consideration that will determine whether or not all the lights stay lit is where they are plugged in. If they are plugged into a circuit that is not already under heavy load, it would take a large number of lights to trip the circuit — more than most people will ever use at one time.

Something to Add? Tag Cloud. During my tenure at Root Electric, I lead the transition of Root Electric from a primarily sub-contracting based business model to a prime-contracting based business model. Accomplishments have been made by developing a team based approach to researching and implementing a service-specific client management system. My goals for the next five years are to fine tune Root Electric's brand strategy and to diversify its scope of services, while remaining true to the discipline of electrical work.

About the Author During my tenure at Root Electric, I lead the transition of Root Electric from a primarily sub-contracting based business model to a prime-contracting based business model. I unplugged, replugged … unplugged, replugged the string. Then it came to me. I must have caused some sort of short circuit when I jolted the wire.
While shunts serve to remedy an open circuit, fuses work to prevent damage due to a short circuit or any other dramatic increase in current. A short circuit is the opposite of an open current. In other words, a short circuit is caused when electrical current finds an unintended path of lower resistance. At a steady voltage, this causes a spike in current, which can cause a variety of problems -- some mild increased rate of incandescent bulb burnout and some severe system overheating and fires.
Fuses are important safety features for many electrical appliances, but most of us don't even know that they're there. In holiday lights, the fuse can be found near the part of the strand that plugs into the wall, often called -- and I'm not making this up -- the male end of the wire. Normally, the fuse is accessible through a small plastic door in the plug that can be opened and closed for replacing the fuse. As the electrical current within a wire increases, the wire can heat up, at times causing melting or even fires.
When the current increases past a safe level, instead of the wire melting or your Christmas tree catching fire, the fuse safely opens the circuit, averting many disastrous scenarios.
Fuses are typically small sections of replaceable wire, rated to a maximum current level. Because they are more delicate than the rest of the wiring, a fuse will burn out before overcurrent has an opportunity to overheat other portions of the light strand. When a fuse breaks, the circuit becomes incomplete and current cannot flow through the remainder of the circuit. LED holiday light strands are becoming more popular. On top of that, they are significantly less likely to burn out or break compared to their incandescent forerunners.
Why is this? While incandescent light technology is relatively straightforward a heated filament glows much like any ember in a fire , the mechanics of LED lights are much more sophisticated. When current is applied to the system, electrons from the negative side move toward the positive side.
When an electron and an electron hole collide, a small amount of energy is released as a photon. The result is the visible light we see in an LED. LEDs are wired in series-parallel just like the traditional bulbs we described above.
