Good morning there I have a standard light fixture with 2 standard 60 watt light blubs hook up to a dimmer switch. We have notice over the past month when we turn on the lights to medium they flicker. But then lst night we had the lights on medium then they flicker then they went off for about a second. Today I check the wires on the dimmer switch to make sure they where tight. Also I took off the fixture to make sure the wires where tight in the ceiling and they where. There is also no bare wires being expose.
This happen when the lights are on low or medium or even high can it be the bulbs
Or the fixture it seft

Thanks

I would remove dimmer, connect 2 wires, if it stays bright, it is the dimmer.
