Lightbulbs in Ceiling Fan!
If the pull chain does not make them light up, then the cheap China made plastic bulb socket is shot. If here is signs that it is defective, contact Hunter. We had the pull chain go bad on our 8 year old Hunter fan in our Master Bedroom, and just replaced with a remote control. Of course, that took taking it down, and connecting the leads of the pull chain switch together, but now I do not have to climb on top of the bed to turn off the light, when the fan runs 24/7.
