Flickering light

I tore down a wall in my basement and am building a bedroom. I wired a 3-way light switch across the room with 2 light fixtures. One of the fixtures flickers constantly. Depending on the combination of how I turn on the switches, the other light fixture may flicker instead. I replaced the bulbs, the light switches, and the fixtures, but am still getting flickering.

I've done a bit of wiring, but have never encountered this before. The 3-way switches are wired normally, but I can post a diagram if necessary. Would someone please offer me some advice?

Thanks,
Paul

You didn't use the back stabs on the switches, did you?

Were they new switches? Were they from the 39 bin at BigBox? If you can't find a loose connection replace the switches, preferably different manufacturer or better quality.

Did you use the wire nuts that came with the fixtures. They are often low quality "fake" wire nuts containing no spring. If so replace with good quality wire nuts.

Thanks again for your reply. I used brand new Leviton switches from the home despot. I replaced all the wire nuts today with brand new ones. Still flickering.

By what you write, I think you suspect a loose connection. All the wires are new except the blk/wht coming from the house, and all the connections are solid. Is there a tool with which I can test the integrity of each leg of wire? If I don't figure this out soon I will call an electrician.

Best,
Paul

Leviton makes high quality switches and economy switches. No guarantee the factory in China didn't make a bad lot of switches. That is why you need to buy different switches. Everyone of the ones from that lot on the shelf could be bad. A couple of $3 commercial grade switches are cheaper than an electrician. Not saying it is the switches but it is a cheap test.

You have two three way switches feeding two lights. The feed should come out of one of the switches to the first light and then to the second light. If that is correct.... it can't be your switches of both lights would flicker at the same time.

What kind of light fixtures and bulbs are you using ?

The problem was that the fixtures were wired in series. Thanks for your help.
