Indoor Flood Lights Constantly Blinking

There are 3 floodlights in my kitchen ceiling that are attached to one switch. One of these lights started flashing quickly (like a strobe light) a few weeks ago. I had to turn the dimmer switch to off to stop it. I checked the bulb and it's fine. Then for a few days, it was okay. Now they are all flashing at once and there is a humming sound coming from the switch. I don't know anything about all this. Do I need to call an electrician? Is it dangerous? Thanks in advance for your help.

Welcome to the forums.

Most of the cans have thermal switches that shuts off the bulb if the fixture gets too hot.
It could be a bulb just slightly too big for the fixture or the heat sensor is going bad.

Have you replaced the bulb recently ?

It might also be possible that the switch is bad if they are all cycling off at the same time.
The switch could be bad or the wattage of the bulbs exceeds the switch capacity.

Double check the bulb wattage and compare that to what the fixture is rated for then compare the total bulb wattage to the switch rating.

I hadn't read that all the lights were flashing at the same time. That would most likely require a switch replacement.

Are these incandescent or fluorescent or LED? (Floodlights may have any of these three technologies inside.)

You may have fluorescents that are not compatible with your dimmer.
