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!
