Probably the switch mentioned above, but I will add my own experience.
I had both headlight bulbs die within one day of each other. It was uncanny. If I hadn't been paying attention and already installed the Eastern Beaver relay, I would have blamed the switch.
So, there is the possibility that the bulbs have just died, but you want to install the relay regardless. And fix the switch if it's fried.
I can also mention that my fuse box has been known to suffer from slow main fuse melting which has caused my headlight circuit (among other things) to fail. There's lots of draw on that baby in the winter when I'm running full heated gear.
If you're swapping out the bulbs, consider going LED. Way less draw and simple plug and play.
