Why Lights Flicker or Blink: Common Electrical Causes

One blinking lamp may point to a local lamp or fitting issue, while several lights flickering together can suggest a wider circuit or supply problem.

Check the pattern

Does the light flicker continuously, only when switched on, or when another appliance starts? The timing can narrow down possible causes.

Watch for heat or smell

Turn off the affected light and arrange an inspection if the fitting, switch or nearby surface becomes unusually hot or there is a burning smell.

Use a photo or short video

Visual evidence can help show the type of fitting and the exact behaviour before a site visit.
