I installed a PD-6WCL switch about 15 months ago, which controls 2 outdoor lights. I noticed one of them flashing off/on early in the morning (the other light isn’t within view of the house), and turned the switch off as I left the house. When I returned to do some troubleshooting, the green LEDs were off, and the switch is unresponsive. I removed the switch and tightened the wire connectors to see if that was the problem, but it wasn’t. Any ideas? Or has the switch gone kaput already?
