A year & a half ago my kitchen was remodeled. I have 3 upper cabinets with glass doors that have lights in them. They're all on one switch.

Last week I noticed that the lights in all 3 cabs would occasionally dim simultaneously. Then they would randomly begin to pulse lighter/darker. Whenever I tried to show my husband, I'd turn on the switch & they'd work normally.

Finally, they acted up when he was around and he thought the switch was faulty. He replaced the switch today, but that didn't fix the problem.

Any idea what would be causing this? These are tiny lights on a strip. All of the little bulbs light up - none are burned out.
