The ceiling light fixture in my kitchen is acting very strange. It's been odd for several years but getting worse. It holds 3 bulbs, and one socket is fine. The other two, however, have been blowing light bulbs at an ever-increasing pace until I just stopped replacing them at all and lived with just the one one bulb. The last time, the bulbs lasted about three days before going out. Is this a sign of something serious? Or just an annoying and expensive quirk? Should I bother with an electrician? This problem predates the SVS subwoofer, so that shouldn't be it.
