I just noticed my hall light is blinking on and off rhythmically, with the switch off.
There are 3 different switches that will turn the light on. I tried each and the light turns on, but when you switch it off, it starts blinking on and off again.
I replaced the old light fixture with a new one 3 or 4 years ago and it’s been fine up until now. I’m pretty ignorant about electrical stuff.
Any ideas what would cause this?

I found if I carefully put the stairway light switch in the middle position, the light is off and doesn’t blink.
I take that to mean that simply it’s just that switch has gone bad and needs replacement?

question #1 what else is powered by that same circuit ?

Until the issue is diagnosed I would not leave the circuit breaker on for extended periods beer

One could turn the breaker off, and then bypass or replace the suspected switch. popcorn

The upstairs lights are all on that circuit breaker. The west and east side wall outlets are on 2 other circuit breakers.

Silly question #2 Are there any LED bulbs in the lights on that circuit ?
It may be just a bad switch but sounds a bit strange shruggy

In fact, the hall light burned out last month so I replaced the incandescent light bulb with an LED.

Change the bulb. It can be another LED bulb, but change it out with a known good one.

I only use LED's and have had a couple of 'bad' bulbs. I have had where the light would flicker, but not a full 'on, off, on, off'.

The light strip over my bathroom sink takes 5 bulbs. I switched them all to LED when I moved in 9 months ago. A couple of months ago, one bulb started coming on slower than the rest. Still lights just as bright, but there's like a 1 or 2 second delay compared to the other bulbs. I tried that bulb in different sockets with the same result.

Is there a dimmer involved??If you introduced a new style led,or LED bulb,,,you need a new style dimmer compatible
with them

No dimmer. Just a standard ceiling fixture in the upstairs hall with 3 switches in various locations that turn it on and off.
I tried changing the LED out for a standard 75W incandescent from my stash. It doesn’t blink now with the switch off, and turns on when the switch is turned on.
So I guess it’s an issue with the LED bulb?
Oh well a $2.00 switch from Menards and 15 minutes swapping it out isn’t too bad compared to any throwing parts at trying to fix a car problem excercise I’ve done over the years! grin

The LED was picking up some residual current from somewhere,not uncommon.

Once again, I'm talking to myself. Glad you figured it out.

My kitchen overhead lights flicker after turning them off sometimes. It's something to do with the fixture and adding LED to them. I could swap out a few parts to get them to not flicker, but I haven't gotten around to it yet.

I appreciate everyone’s input and advice on this issue! beer I hadn’t thought it might be something as simple as quirks with LED lightbulbs. I figured for sure it was issues with my houses 60 year old wiring or a bad switch.
I hoarded a bunch of incandescent lightbulbs away when they were phased out. I’ll be set for years to come!

I think it's the circuitry in the LED bulbs that holds power a bit and does it. I have a nightlight in my trailer that looks like it has an LED bulb in it judging by the color of it and it'll be on even when there's no 120V power and no voltage at the plug.

I would be tempted to replace the other two switches as well.

If one switch isn't completely open, it can still pass some voltage/current, (enough for the LED to notice, but not the incandescent), while holding another switch half way may be enough to completely break the circuit.


If you ever find yourself in a fair fight, your tactics suck.

I have switches that light up when the fixture is off. With LEDs in the fixtures, some brands of LED lamps will flash due to the small amount of current through the light up switch.

I had the same problem, mine turned out to be a lighted switch. The switch would pass a small amount of power to the LED and when the capacitor in the LED got charged enough it would come on like a flash bulb every 10 seconds or so. If you have a lighted switch, take is out and try again.
