New PD-5ANS shows dim LED when off, bright LED when on, however it is not turning on the light. If I pull the FASS switch out and put it back in when the switch is showing the bright light, the lights will come on, and the switch will properly turn the lights back off when the off button is pushed, but will not turn them back on with the on button (led gets bright though). Only way to get the light to come on is to pull the FASS switch out and push it back in while the switch is in the on position. Lights are 2 120v 150W max halogen lamps. Bulb is the ~4" long tube with contacts on each end. Box says this switch is compatible with halogen up to 600W. Any ideas?
