With DRLs still activated it makes sense, doesn't sound like a sign of a bigger problem, but I'd replace them both to see if one consistently goes out sooner than the other.
If your looking for long life, than your standard halogen will be your best bet. They are not that expensive anyway, so who cares. I believe Sylvania makes a Long Life bulb. Any of the White/Hyperwhite/HID-look bulbs (Silverstars, PIAA, Nokya, etc.) run hot and burn out much quicker.
