Radio got loud and full of static and the headlights went out?

Hi, I own a 2002 Dodge Ram Conversion van, 1500. My wife was stopped at a red light and all of a sudden the wipers turned on, the radio got loud and full of static and the headlights went out. I checked and both headlights were burned out, the wiper fuse was blown. When I replace the wiper fuse and you start the van, the wipers stay on and can't be shut off. I have not replaced the headlamps for fear of them just blowing again. The voltmeter shows just over 14 volts and the van runs fine. I was told it was possibly a power surge due to a bad regulator.
Any ideas?
Thanks so much.
Bill
