Homeowner field note
When flickering lights deserve a closer look.
One loose bulb is usually simple. Repeated flickering across several fixtures, buzzing switches, warm outlets, or breakers that keep tripping can point to a wiring, connection, or circuit issue. Turn off anything that seems unsafe and have the problem professionally assessed.
This general information is not a diagnosis. For immediate danger, leave the area and contact emergency services or your utility as appropriate.
