Need to check all the bolts and make sure there tight make sure the chain or belt is tight also.
to much vibration is knocking out your filaments. I use regular bulbs in mine havent changed them in 3 years.

I had the same problem, started using CFL bulbs instead. No problem now.

Use yellow / white light bulb
not the yellow bulb

Try REVEAL brand DOUBLE LIFE ceiling fan light bulbs, available from HOME DEPOT. The filament in those bulbs is much thicker than any others, and the one I installed on my own Sears GDO has lasted 3 months so far, compared to one week for others I have tried.

the small metal tab at the base of the socket. Clean away any
corrosion you may find on the tab as much as possible. With a small
instrument, generally pry up on the metal tab to ensure that it will
make solid contact with the light bulb.
