Most Incandescent string lights are wired in a series which means the electricity must pass through each bulb to complete the circuit and a single bad bulb can make the whole string go dark. In the cases with Larger light strings, they may contain two circuits and only one section of the string goes dark.

A Hassle-free way to find faulty bulbs on incandescent Christmas lights is with a Christmas light tester. Just bring the light tester close to each bulb. if the tester’s indicator doesn’t light up then the bulb is not functioning.

While using a non-contact voltage detector, bring the detector close to the wire section between each bulb to test voltage. The bad bulb will be in the dead section of wire.

We all know the tiring process of changing bulbs that’s why everybody is making the switch to LEDs especially if you’re concerned about light safety then LED bulbs are the right choice for you. They use less energy, produce less heat, and last longer.

Finding Bad Bulbs on LED Christmas Lights

Usually LED Christmas lights are made without removable bulbs, so the circuit won’t fail if a single bulb breaks.

In the case of LED Christmas lights with removable bulbs, the troubleshooting process is similar to incandescent bulbs. 

The next long road approach is replacing all the bulbs if you don’t have any voltage detectors or other tools but you do have a replacement bulb, by going down the whole length of the string and switching out each bulb, checking to see if that solves the problem each time. 

How to Replace the Bad Christmas Lights

While replacing the bulbs remember to replace incandescent or LED bulbs in the correct voltage rating and colour. Always follow electrical safety by unplugging your lights before removing or replacing any bulbs. Carefully screw in the replacement bulbs and plug your lights back in. If you have replaced the bad bulbs on your Christmas lights but you still experience problems, the issue may be bad wiring. Consider replacing the lights at this point.
