We have a new home (3 years old) We have small fluorescent lights mounted under the cabinets which are wired in sequence so they all come on at once from one switch. We frequently have lights which begin to flicker. I can wiggle them some and they quit flickering but eventually they will not quit flickering and we use the individual switch to just shut it off until we purchase a new bulb. We have probably replaced every one of the bulbs at least once and some twice. This just doesn't seem right. Does any one have any ideas as to what the problem can be?
