I was out for a ride yesterday and while on the highway I had the cruise set. My ride took me on about 20 miles of highway then about 80 miles of back roads. So once I got off the highway I turned off the cruise control switch. After a little while I look down at the dash and see the amber cruise light is lit even though the switch is turned off. I toggle it back and forth and the light goes off. So after another 10 miles or so it happened again. This time I hit the set button and the cruise came on, and the switch was still in the off position.
Is this just a bad switch? And let me guess, I cant just buy the switch, I have to buy the whole switch/control assembly with the high/low beam and horn and turn signal.

 

Probably the switch but to confirm you would need to eliminate the switch from the equation. That will produce it's own challenges for you, but necessary if you don't want to shotgun it by replacing it first.
