Ceiling fan light bulbs blowing out
In our living room, the ceiling fan has four light bulbs, and we need to replace them at least every 4 weeks or so. They are 40 watt, 120 volt lights. They always blow out when they are NOT on. I've heard it quite a few times - during the day when we don't need the light on, you can hear the distinctive 'tink' sound that a bulb makes when blowing out, and sure enough, next time we turn the lights on, one has blown out.
I'm not sure what to make of it, and am concerned that there is something wrong with the wiring and that it could be a fire hazard. We recently had our heat pump motor blow out and start a fire in our crawl space, so I'm kind of a nervous nelly about fires right now. If anyone has any ideas, I'd appreciate it! Thanks.
