Two things I can think of.
The headlights should be operated through a relay that may have stuck on. Replace the relay.
If you have DRL (daylight running lamps) how are they operated? Some are oil pressure activated, some air activated when you release the brakes, and some are just wired to the ignition hot. Again they probably operate through a relay.
If you are sure the only thing you did to correct the problem was cycle the headlight switch, then I would say it is either the relay or the headlight switch itself.

Anyone else have this issue?!
