I have 3 under-counter lights in my kitchen. These are the small 13 watt lights. I like them quite a bit and they are only 5 years old.
All 3 are connected to 1 switch.
About 4 months ago they all started having trouble coming on. They would start, but mostly dimmed and with a buzzing sound. When I would flick the switch off and on, sometimes they would turn on and sometimes they wouldn't.
That got worse and worse. Finally I bought 3 new light bulbs. They mostly all 3 come on now, but from time to time ONE of them doesn't come on. Then I flip off and on the switch - that one light comes on.
What is left to fix or replace now that I have put in new light bulbs?
