Flickering Lights in Multan: Causes and When It Is Serious

Lights that flicker or dim for a second can be harmless, or an early sign of a wiring fault. This guide to flickering lights Multan homes notice, especially when the AC starts, explains the common causes, what you can check safely, and when to call an electrician.

The Short Answer

If one light flickers, the bulb or the fitting is the likely cause. If lights flicker in several rooms, or flicker whenever a large appliance starts, the problem is in the wiring, the supply or the load. A burning smell, a buzzing sound or a hot switch means stop and call an electrician.

Causes Limited to One Light

• A loose bulb or a worn holder. The connection makes and breaks.
• A failing LED bulb or driver. Cheap or old LEDs can flicker or buzz.
• An incompatible dimmer. Some LEDs do not work properly with older dimmers.
• A loose connection at the switch or fitting. This can get worse over time and heat up.

Causes Across Several Lights

• A heavy appliance starting. An AC or motor draws a large current when it starts, which can dim the lights for a moment.
• Overloaded circuits. Too many appliances on one circuit.
• Loose wiring in the distribution board or a joint. This is a safety risk.
• Supply or voltage fluctuation. Variations in the incoming supply can show up in the lights.

Checks You Can Do Safely

1. Switch the light off and let the bulb cool, then check it is screwed in firmly.
2. Try a new bulb of the right type in the same fitting.
3. Note which lights flicker, and when: all the time, at certain hours, or when an AC or pump starts.
4. Check whether the flicker stops when you switch off a large appliance.
5. If you use a dimmer, check that the bulb is marked as dimmable.

Warning Signs

• A burning smell from a switch, fitting or board.
• A buzzing or crackling sound.
• A switch or socket that feels hot.
• Lights flickering throughout the house, especially with a tripping breaker.

What Not to Do

• Do not touch wiring or open the board while the power is on.
• Do not ignore flickering that comes with heat or a smell.
• Do not replace a breaker with a higher-rated one.
