You can take a few steps to prolong the life of your holiday lights. Make sure to replace burnt-out bulbs as quickly as possible to avoid overloading the rest of the circuit and knocking out more lights. Before packing them up each year, plug each strand into the wall to confirm everything is still working. Wrap the lights carefully back into their original packaging or something similar—winding a strand tightly together or leaving it to hang loose in a storage bin can lead to frayed or damaged wiring. 

Outdoor lighting repairs typically take between 1-3 hours. The exact duration can vary depending on factors such as the complexity of the problem, the extent of the damage, and the ease of access to the lighting fixtures and wiring.

If half of a string of Christmas lights is out, it is likely because of a single burned-out, loose, or broken bulb within that section. Long strands of lights often contain more than one circuit, so when one bulb fails, it can cause the entire circuit (or half the strand) to go dark. To fix this, inspect the unlit section and test each bulb to ensure it is tight and functioning properly. Replacing the faulty bulb or repairing a damaged shunt will typically solve the problem.

There are a number of reasons that landscape lights burn out, including an incorrectly installed transformer, inconsistent voltage, and burned-out or faulty bulbs. Troubleshoot landscape lighting problems by first determining whether it’s a system-wide problem or an issue with just one light, which will help you get to the bottom of your outdoor lighting woes.
