Try using matched bulbs. I've had this problem with other makes of cars. Plus make sure you don't touch the bulb with your fingers, or the oils from your skin will cause the bulb to fail.
I have the same problem with my Mazda 5. I've used every make of bulb available. Nothing works for long. Now I'm keeping the bulb packages and returning blown lights under warranty.
I used to replace my headlights once a year when I was using Sylvania bulbs and no I do not touch the bulb with my fingers. About a year and a half ago, I went to Meijer and got Philips Bulbs instead. So far so good and that's the brand I will stick with for this car. At least it only happens to the low beam (I have a Pro5 and the high and low beams are in separate bulbs).
If you have that many trouble with bulbs, try switching brands. Even though you said you have tried everything, keep trying. Good luck.
The P5 must have a voltage issue. My 2002 P5 has now gone thru 5 light bulbs (4 low and 1 high) within a 2 year period. Lucky I have been able to replace 3 of the lights under warranty periods.
I have owned the car for 6 years and all these problems have occured in the last two years. I have had to replace two batteries and an alternator in the past 2 years. There is definitely an electrical/voltage issue.

It is more than two years, and same bulbs still. Don't know if it was Sylvania, or whether I lucked out without any voltage issue, but the set of Phillips bulbs had lasted over 2 years and are still working. Good luck to all those who still own this little car to find a solution for the burnt out headlights.
It could be vibration. I used to have motorcycle that killed all electrical parts with vibration. If the motor mounts start to harden with age the vibrations could be more than the filaments can handle. Just a suggestion.
This isn't a headlight issue with my 2003 Mazda Protege 5, but I am pulling my hair out trying to figure out what is going on with it. Bought it as a used car, drove off a day later, and the check engine light came on followed by the battery light, had both tested. Battery was good, so I replaced the alternator. For 2 days it ran like a dream. Next thing I know the check engine light and battery light come on again.
If the battery light is on and I have to stop in town, it starts to rev up like it's going to blow up. Also when the battery light comes on, it starts to jump and jerk like crazy going down the road.
Here is the strangest thing of all, just as soon as that battery light comes on, a minute to 5 or so later it will go off and the car drives perfect! I love this car and don't want to give it up. It's only got 68,000 original miles on it and drives like a dream... HELP. If anyone has any ideas, please let me know. I replaced the Internal Air Filter thinking that was it... NOPE!! If you have a clue, please contact me at firstname.lastname@example.org, my name is Lea. Thanks for your time.
