I bought these two sconces for my bathroom, I have connected to the same circuit and they light simultanéement with the same switch, but one of them has the annoying habit of start flashing regularly. I checked the connections between the son, but they seem quite correct, I think of a fault on a weld or cut a thread in the hinged part (12 volts after the transformer) or defect of the integrated transformer when it heats up (after one minute). unfortunately.
