Both headlights failing at the same time???

How's this for a bizare problem:

I have a 2000 Honda Civic HX with the CVT. I drive about 400 miles a week
commuting, so it's up to 107K miles. And I always drive with my headlights
on, day or night.

Last fall, coming back from Rockford, I realized that BOTH headlights had
failed at the same time. OK, after 5 years, they didn't owe me anything, but
having both fail at exactly the same time was a bit of a coincidence. I
replaced them with a pair of the (Wagner?) blue HB2 bulbs.

This morning, pulling out of the garage, I realized that both had failed
together again. This is NOT a coincidence. They should definitely last more
than 5 months, and shouldn't be failing together. Only the low beam is
blowing, not the high beam, because I rarely use the high beam. Maybe I
should use the high beam for DRL and save the low for night driving?

Any ideas on what could blow both bulbs at the same time, yet not affect
anything else on the car? I can buy a case of bulbs for less than what it
would cost if I ask a dealer to look into the problem. But it's a nusiance
to never know when I'm going to be left in the dark again.
