I think it might be that the connector to the horn has come off (this is not that unusual). If the interior lights are connected in series with the horn, they would go as well. The horn connector is found sometimes in the horn pad, or in the dash just under the instruments, or within the steering column cover.

That's where I got my picture from. I realized it had the wiring diagram after I posted here. Thanks for confirming it. Pooh Bear

Treat the problems as seperate issues, and accurately diagnose one at a time.

I was going to put my blood type on the helmet too, but an EMT told me he would never pay attention to what someone claims their blood type to be, he uses universal plasma and at the hospital they use a quick blood typing test. The risks of infusing an incompatible blood type are too high. Medical insurance information sounds like a good idea. Although [rant] have you checked what your "insurance" actually covers, lately? Our family of four pays about $16K/year in employee contribution. And our total family deductible is around $12K/year. We have not consumed over $12K/yr of medical care in at least ten years, probably not since the last child was delivered. Basically we pay $16K/year - and my company pays at least as much - for catastrophic coverage. On a day-to-day basis, every doctor visit and every prescription is coming out of my pocket. I'd rather we had the system they have in France. Everyone, rich or poor, has basic, no-frills medical coverage. Those who want nicer, fancier, more sophisticated treatment - private rooms, cutting-edge technology, $100K/yr drugs - have the option of buying commercial insurance policies, if they can afford it and want to. But everyone, rich and poor, has a basic and decent level of care. We may get a version of that in the US, starting in 2014. Maybe. "There's many a slip, 'twixt the cup and the lip." Who knows if it will actually happen. [/rant] After reading this http://www.nytimes.com/2012/07/21/technology/bicyclists-using-cameras-to-capture-accidents.html I got interested in wearing a video camera, so you see on the helmet my initial experiment. It is not the $300 GoPro that a serious biker-recorder wears, but a $38 micro-cam from a Hong Kong mail order hobby shop. Meant for use in radio control aircraft, helos, etc. After experimenting with this cheap camera, I'm putting a nicer videocam on my Santa list. Aside from the "evidence" aspect, it is instructive to view a recorded ride and think about what dangers I did and didn't perceive at the time. I've been riding in traffic since I was a 7 y/o boy riding in downtown Vancouver B.C. on my Peugeot ten-speed, but I still make mistakes every day. Just like we all make mistakes driving, even though we've been doing it all our lives. I'll post a link to some video later. Here is a link that might be useful: NYT Story
