There was a factory defect that FR was doing warranty work to replace. ITC is the manufacturer, but the problem is much more widespread than they like to think. Our Legacy has six bad ones so far of the twenty fixtures total. Contact ITC; supposedly they will replace them so long as you're outside the one year warranty and don't mind installing them yourself (just two wires). Working with our dealer is terrible, so I'm riding out another month under the warranty, then going back to ITC.
