I was more curious if it was possible there was some electrical anomaly
causing this and if so, how I could find it.

I'm not opposed to CFL, and if my investigation turns up nothing I'll
probably switch to CFL.

You can get a "rough service bulb". These are made to withstand vibrations.
And being next to the door, when the door closes, this may be vibrating the
bulb. Especially if you have kids running in/out.

Or might try compact fluorescent.

LED bulbs are quite expensive and not as bright, but will last forever..

About every 5th time (+/-) the light is turned on the bulb blows.
Sometimes it can go a dozen times, sometimes just a couple times.
There are other lights on the same circuit and they don't experience the
same problem.

I'm going to get into it this weekend to check the line voltage and make
sure all of the connections at the light and switch box are secure and
insulated but I can't imagine a loose connection or even a short would
blow a bulb (am I wrong on this?).

What else should I be looking for?

Thanks in advance!

I had no kids and didnt slam doors either and my �porch light was
always blowing out too. �It was due to vibration, but strangely, the
rough service lamps didnt fare much better than the regular bulbs.

What fixed it for me was going to the high voltage �130V bulbs. Ace
Hardware sells them. �They have a beefier filament. After switching to
them, I never lost another bulb in that fixture. �They are less
efficient though.

You could also try CFLs. If you live up north, you need to check the
label and get one rated for -20 degrees.- Hide quoted text -

might be caused by bad socket that gets overheated because of poor
connection and causes bulbs to burn out. I have had this
happen..........
