I had the same exact problem with the Blue Funk, Al. Everything EXCEPT the instrument lights worked.
Having more money than sense, I went ahead and replaced the headlight switch. The old one was pretty tired-looking anyway.
You can order a replacement switch for about $25 from Classic.
Or- you might just try removing the headlight switch and cleaning up the connections. If nothing else, it'll give you some experience fiddling around with the electrical system.
In the past, I've avoided fixing things because I've broken things more than they were already broke.
So from one novice to another, it's a little difficult to break a headlight switch. Especially one that's already broken. Or not.
Good luck to you, Al.
