HB-4190 Motion sensing lantern. I have had 2 of these lanterns on one switched circuit for more than 1 year. Recently they both quit working properly. They both come on at dusk, but they do not go out after the set time. They no longer go out after dawn. There have been no changes to their circuit or their wiring. A third light that has always been on the on this circuit is a dusk to dawn photocell operated lantern; it still works properly.
