My house has recessed lighting-about 4-10 lights in the ceiling per room. Recently, I replaced several lights that had burned out, but found that one light in the study and one in the bathroom still didn't work even with new bulbs. Other lights in those rooms work fine. Is this something to worry about? COuld it be problems with the wiring? The lights used to work.
If the lights lit for a short while then went out it could be that the bulb was too high of a wattage for that fixture and tripped the thermal protection built into that light.
