Why Are My Lights Blinking?

Blinking lights could signify a minor electrical problem. In addition, flashing lights can prove annoying. You can seldomly work well in a house with disrupted visibility. Understand the causes of blinks and flickers below.

1. Your Bulbs Are Loose or Faulty

The most direct cause of flickers and blinks is an issue with your bulb. The connection between your light base and the lamp cord loosens when the bulb is loose. As a result, an open circuit gets created, and your bulb flickers until you resolve the problem.

Damaged bulbs or those that operate in an unsuitable environment are also prone to blinks. For instance, LED bulbs flicker more with dimmer switch lights. Finally, bulbs become loose in the sockets with age and lose connection with the socket tab. The interrupted connection causes your lights to flicker.

2. Your Transformer Has Technical Hitches

Your bulbs are a component of an electrical connection within your house and neighborhood. You likely share a transformer with your neighbor based on your local electrical connections. One of the downsides of a shared transformer is that your power is affected by your neighbors' electrical usage.

When the transformer develops a hitch, or your neighbors draw a lot of power, the voltage in your home could dip. In such scenarios, the hitch happens to your home and nearby premises. Transformer issues are beyond your control. So, the ideal action is to call your electrical company to undertake the necessary fixes.

3. Your Voltage Has Dipped

Electricity gets supplied to your home in standard voltage values that you can measure with a voltmeter. Voltage fluctuations are evident in lights that flicker shortly after switching a major device on or off. A dip in standard voltage reduces the power that flows to your bulb and causes your lights to blink.

Sometimes, voltage fluctuations are normal and should not worry you. Turn off the major appliances and lights until the voltage returns to normal. If the problem is consistent, call an electrical expert to check your circuit breaker and power supply switch.

4. Your Wiring Has Gaps or Is Loose

Wires transport the current to your bulbs, so interference with the wiring system makes it difficult for the current to pass through. In addition, loose wires leave gaps that need electricity to transmit from one section to another. Since the problem is consistent, lights that flicker due to gaps in wires do so consistently. Wire hitches are common in old homes with outdated electrical systems.

Loose wires predispose your premises to electric fires. That's because electric current struggles to jump through the sections of the cables and could ignite close-by material. Also, loose wires overheat, leading to temperatures that can cause fires. If you suspect you have loose or faulty wires, turn off the main supply immediately and call an electrician.


Other than loose or old bulbs, many other electrical faults are not a DIY job. If you attempt to resolve the problem without the necessary expertise, you risk your safety. So, always contact a reputable residential electrical services company to inspect and solve electrical hitches.
