Are you purchasing the better line of bulbs or cheaper line. Also check for dirty or discolored pin in the connector, maybe need to be replaced or cleaned to a shine condition.
Dont touch the glass with bare hands!! Oil from your skin gets on the bulb will shorten it's life!! Fact!! Got to have clean bulbs! Also check for poor connections causing high resistance/heat!!
