A strange post-storm symptom at one U.S. home turned out to be an electrical warning sign that's easy to miss.
There was no outage, no obvious smoke, and the only change was lights suddenly shining much brighter than normal.
Here's what to know
After the storm, a homeowner noticed an unusual change inside the house. On Reddit, they said that the bathroom and hallway lights were suddenly far brighter than before.
Lightning seemed to strike either their house or somewhere very close by. Concern in the thread rose further when the poster added, "the bathroom light has now gone dim."
Commenters in the thread said it can point to a serious problem that could put household devices at risk.
"This is an immediate and serious concern," said one person claiming to be an electrician

They said the most likely issue was "a damaged neutral connection at the transformer," which can leave some circuits receiving higher voltage while others get less.
Rather than causing a straightforward blackout, commenters said this kind of fault can show up as uneven electrical behavior across the house. They warned that those voltage swings can damage devices, and another person in the thread described changing brightness as a classic warning sign of a loose neutral.
More background
Electrical storm damage is often associated with tripped breakers, downed lines, or a full power loss. But the original poster said there was "no flickering or power outages" when the lightning strike happened.
Commenters said that the lack of an outage did not rule out a problem and could instead mean the home's voltage was no longer stable from circuit to circuit.
In an update, the original poster said an electrician was being sent out and added that "we unplugged everything not in use until then," suggesting the family was trying to limit any preventable damage while they waited.
What can be done?
The advice in the thread was to treat unusual lighting changes after a storm as something that needs prompt professional attention. When the original poster asked what to say to the utility, a commenter had a simple suggestion.
"Just tell them exactly what you see," the Reddit electrician instructed. "They will ask the right questions to try to see if there is a concern or if it might be something else."
Commenters did not all suggest the same temporary step. One advised turning off or unplugging devices until the issue is diagnosed, while another said flipping the main breaker may be safer than unplugging loads one by one in some scenarios.
The original poster ultimately agreed the warning signs were pointing in the same direction.
"I fear it's just as everyone said!" they wrote. "I knew it would go dim sometime. Thank you for the helpful suggestion, I will be calling the local service provider!"
Where can I learn more?
Storm damage doesn't always show up the same way from one house to the next. Backup power can help keep the lights on when a storm hits.
• After a hurricane, one homeowner found solar panels kept lights on when neighbors went dark.
• A portable battery can help keep essential appliances running in a blackout without the need for a whole-home backup system.
