Have you tried to turn it to "ON"? Dumb question, but I had to ask. If you have, it does sound like the switch ass'by. Replace.
If it were just the bulb, probably, but it electronic - anything can happen. I do not have your year schemetics, so I can not send you the electrical diagrams. I still say it is the Headlamp switch tho....or there is a broken wire going to the lamps.
