Flickering light diagnosis starts from $80 at SG QuickFix. LED lights that flicker, flash, buzz or glow when switched off usually have a failing driver, a loose connection, an incompatible dimmer or a switch letting a small current through. The cause is found in about 30 to 60 minutes and the fix priced before any part is fitted.

Task guide

- Lights flicker after a dimmer or smart switch was installed.
- Several lights flicker together.
What the team does
The technician checks whether one light or many are affected, which separates a fitting fault from a circuit fault. The fitting's driver and connections are checked, along with the switch: a smart or illuminated switch, or one wired on the neutral, can leak current to an LED. Loose connections are remade on the spot. A failing driver, an incompatible dimmer or a wiring fault is priced before replacement.
Included in this price
- Checking whether one light or the circuit is affected
- Testing the driver, connections and switch
- Remaking loose connections
- A price for drivers, dimmers or wiring repairs
Limits & price factors
Replacement drivers, fittings and switches are priced separately. Circuit faults affecting many lights may need circuit fault tracing.
The price starts from $80. Lights in high or hard-to-reach ceilings, and faults that come and go, take longer.
FAQs
The most common cause is a failing LED driver. Others are a dimmer that isn't LED-compatible, a loose connection, or a smart switch letting a small current through.
A small current still reaches the LED, often through a smart or illuminated switch, or a switch wired on the neutral instead of the live. The wiring should be checked.
Usually it is a failing driver, but a loose connection can overheat. Several lights flickering together point to a circuit problem that should be checked.
At SG QuickFix, flickering light diagnosis starts from $80.
