It seems as though recently that our light bulbs keep going out... what might be the cause of this?? Just in the last 2 days we've had 3 light bulbs go out. (they have all been changed in the last couple of months!)

Maybe a bad socket or bad switch.

A loose neutral can do that, voltage can go to 240 volts if open, or loose. A white wires(Neutral need to be tightened, or verified tight. Tighten all hots while your at it.
You can get 130 Volt bulbs, They don't run at max, and last longer.
It is possibe for the Neutral to be loose at the Meter. If you question it, because of high and low voltage readings, Don't hesitate to call Electric Company

Additional question: are you putting a bulb that is more than the called-for wattage? A 75 watt as opposed to a 60?
