the service vehicle soon light came on cause I had a headlight out.
The tech told me that any time any sensor goes out, such as a headlight, the service vehicle soon light comes on.

A headlight isn't a sensor. I've had headlights go out, and have never had the service light come on. Was the OBD read for the diagnostic code?
