Is Flickering Light a Serious Electrical Problem?

Yes, sometimes. While flickering can be caused by something as minor as a loose bulb, it can also indicate dangerous issues like wiring faults or overloaded circuits.

Key Warning Signs to Watch For:

Flickering occurs in multiple rooms
Buzzing or burning smell near the switch or fixture
Lights dim when major appliances run
Circuit breaker trips when lights are turned on

If any of the above are happening, it could be an urgent electrical problem that requires immediate attention.

Common Reasons Why Ceiling Lights Flicker

No.	Cause	Description
1	Loose Bulb or Socket	The most common cause. A bulb that isn’t tightly screwed in can flicker due to poor contact or vibration.
2	Incompatible or Faulty Dimmer Switch	Many modern LED bulbs aren’t compatible with older dimmer switches, leading to flickering or flashing.
3	Voltage Fluctuations	Inconsistent voltage causes lights to flicker, dim, or brighten suddenly. Common reasons include: Overloaded grid in your neighbourhood, Issues from TNB (Tenaga Nasional Berhad) and Faulty electrical panels
4	Overloaded Circuit	Plugging too many devices or high-power appliances into one circuit causes surges that make lights flicker.
5	Faulty Wiring or Connection	Loose or aging wiring is hazardous and a leading cause of persistent flickering. Always call a licensed electrician for inspection.
6	Aging Light Fixtures	Old or damaged fixtures can cause irregular flickering and may completely fail over time.
