Why Are My Lights Buzzing?

22.10.2025

Have you noticed a buzzing sound coming from your lights? This can be a frustrating issue, but it’s often a sign of an underlying electrical problem. At Mayne’s Power, we’re here to help you identify the cause and find the right solution.

Common Causes of Buzzing Lights

1. Loose or Faulty Bulbs

A loose or defective bulb can create a buzzing noise due to poor electrical contact. Ensure the bulb is properly screwed in and consider replacing it with a high-quality alternative.

2. Dimmer Switch Issues

If your lights buzz when dimmed, it could be due to an incompatible dimmer switch or low-quality bulbs. Switching to LED-compatible dimmers and bulbs often solves the issue.

3. Electrical Overload

Overloaded circuits can cause lights to buzz due to excess electrical current. If you notice flickering or dimming along with the buzzing, you may need a professional electrician to assess your wiring.

4. Wiring Problems

Loose or aging wiring can create resistance, leading to electrical noise. This is a potential fire hazard and should be inspected by a qualified electrician immediately.

5. Transformer or Ballast Issues

For fluorescent lights, a buzzing sound may indicate a failing ballast. Replacing it with a modern electronic ballast can eliminate the noise and improve efficiency.

How to Fix Buzzing Lights

  • Tighten or replace bulbs to ensure a secure connection.
  • Upgrade dimmer switches to models compatible with modern LED lighting.
  • Avoid circuit overloads by redistributing appliances or upgrading your electrical system.
  • Schedule an inspection with Mayne’s Power to check for faulty wiring or outdated fixtures.

Final Thoughts

Buzzing lights should not be ignored, as they could indicate a serious electrical issue. If you’re unsure of the cause, Mayne’s Power can provide expert electrical troubleshooting and solutions in Torquay, Surf Coast, and Geelong.
