94 headlights blowing

I have a 94 intrepid and in less than 3 years I have replaced the drivers side headlight three times now. Any ideas what could be causing this?
Thanks

The new bulbs if you handle with your fingers will blow in a months time. If you get a finger print use a clean white rag and windex or rubbing alcohol to clean.
Replace any leaking lense as the water evaporating will blow bulbs.

Thanks for the tip, nice to know. It's only the low beam that goes though, could that still be a cause.

I would think it could be a cause as you use low beams 90% or more of the time.
Otherwise a loose ground or positive wire would cause them to flicker.
