I have 3 G4 light sockets built into my kitchen cabinets, to provide downlights onto the counters.

The bulbs would always go out really quickly, but might start working again for a bit if i tapped the cupboard.

Today at the DIY shop i spotted some 1.8W 200 lumen LED G4 bulbs so i thought I'd give them a try.

I put two and tested the lights, which lit up happily. I then added the third and retested. The LEDs all started flickering. They flicker if 3 bulbs are installed, but are happy with 1 or 2.

It doesn't matter which socket is the empty one.

What's happening here? Is my wiring safe?

  • Is there a dimmer involved? Is this 12v or 120v (I believe there are G4 base bulbs in both voltages)

Don't quote me but look into dimmer switch if any for led. Sounds like not enough current or wiring issue. Do you have a multimeter to test the current? Do different bulbs work (3)

  • The halogen bulbs work, but then go very quickly. I think I need a new transformer. Apr 5, 2017 at 19:33
