I purchased 3motion sensor lanterns for outside our home. Two are on the same circuit and flank the garage doors, one is on a different circuit this light is working. One of the two lights does not turn on when on auto mode. I can hear the sensor clicking but nothing happens. It does turn on in manual mode. This is the second lantern we installed, we returned the first one because we had the same problem. We are using led lights which also work in the other lanterns. I changed the bulb in the malfunctioning lantern with no better results. With both malfunctioning lanterns when it was installed and the light was turned on for the first time the bulb flickered for a minute before coming on.
