hmmm i'm going to think outside the box now.

is your alarm wired to your headlights so that they turn on when you first unlock your car?

do you turn on your lowbeams on and off at rapid pace (as if wired to your alarm that goes off frequently)

constant on and off cycling shortens a bulb's (any bulb, household, automotive, etc) life considerably, but you already knew that.

i dunno, i just went throught a debacle with my headlights and i can share your frustration
