I was president of our homeowners association for 8 years and we had the
same problems.  We tried various solutions first shot was to use ABCO
brand blubs, that helped but still had problems.  We determined that our
failure rate was caused by thermal shock (rain on lighted blubs from
broken globes) and vibration (wind, etc. shaking filament).  Our final
solution was:  1)  use blubs (sorry can't remember the brand) that were
commercial type with 3 or 4 filament supports instead of just two, and 2)
replace all globes with plastic equivalents instead of glass.  Since then
we have to replace 2 - 4 blubs per month out of a total of 80 lamp posts.

Hope this helps.
