The last few days the lights in my kitchen have been flickering or barely putting out any light. I replaced all four of them tonight only to discover the same symptoms. The real craziness started when I started removing or swapping them. I started getting light again when I only had 2 or 3 plugged in. One section would be bright while the other was dim or not shining at all and they switch places with which pair was working. Right now the original bulbs are shining bright - but only one pair are in use. Could there be a problem with the wiring in the setup? Both sets of lights are tied to the same switch.
