What happens if my Christmas lights go out?
Written by Backyard Boys Lawn Co., San Antonio · October 27, 2026
Text us and we fix it. Upkeep is part of your price: if a light or a whole section goes out, we fix it within 24 hours of your message, all season long. Our number is 210-595-9546, and you can text it any time, day or night. You never have to climb a ladder, buy a replacement strand or figure out which bulb went bad.
This page explains why lights usually go out, a quick check that brings most of them back in seconds, and the few times you should not touch anything at all.
Why Christmas lights go out
Most of the time it is not the lights. It is the outlet they plug into.
- A tripped outdoor outlet (GFCI). Outdoor outlets are built to shut off on their own when they sense a problem like moisture, which is why lights often go dark the morning after a rain. Electricians list the outlet as the first thing to check.
- A timer that got bumped, or that reset itself after a short power blink.
- A tripped breaker inside the house, especially if a space heater or other big load shares the circuit. A breaker can trip without snapping all the way to OFF, so it is easy to miss. A troubleshooting guide suggests flipping it fully off and back on.
- A bad bulb, socket or strand. This is less common with commercial LED bulbs, and when it happens it is ours to fix.
The 30-second check
You never have to do this. It just fixes most outages on the spot, so your house is lit again tonight instead of tomorrow:
- Find the outdoor outlet your lights are plugged into. On install day we show you which one.
- Press RESET on that outlet. If it rained, give it about an hour to dry first. A lighting contractor in Phoenix told reporters after a storm that the outlet is usually the culprit, and letting it dry and then pressing reset brings the lights back.
- Check the timer, if your setup has one, and make sure it is set to the right on and off times.
- Still out? Text us. We add you to the next day’s repair stops and fix it, no charge.
If the outlet trips again right after you reset it, stop there and text us. That usually means water got into a plug or a connection, and it is a quick fix for us.
When to stop and call for help
Some things are never a do-it-yourself job. If you see sparks or smoke, smell burning, or a wire is down, do not touch the lights or the cords. Unplug at the outlet only if it is safe to reach, keep kids and pets clear, and call 911 if there is a fire. Then text us so we can come out and make it right.
What a repair visit looks like
When you text us, we reply with a quick question or two, and a photo helps if you can send one. Then we come out, usually without you needing to be home, since everything is outside. We find the cause, swap any bad bulb or section, check the rest of the run and test it before we leave. You get a text when it is done.
Is the repair extra?
No. Lights, install, fixes within 24 hours all season, takedown and storage are all included in your price. See what is included when we provide the lights, what to expect on install day, or get your price on our Christmas light installation page.
