As a follow up, to my original post. My Precept has just returned from a visit to the Service center. They found several issues, but mostly that the LED's seam to have an issue, but Jayco will not just replace them all until they fail one by one, forcing me to revisit for service as they fail.
My coach still has one more light that is burned out, and the replacements are back-ordered, so I wait for now.
