I have 3 banks of LED pots, controlled by 3 Maestro switches. They have worked perfectly for 5-6+ years. Today, one of the switches would not turn on (green indicator is on the lowest setting). Two of the LED bulbs are now pulsing (8 bulbs in the bank and the pulsing bulbs are in opposite corners).Does this indicate the switch has reached end of life? If one bulb were to have failed, would this cause the issue? Thanks
