They are obviously illegal on open water, but I would argue the illegality of this rig on the ice. As long as you are attending them , have no more than 5, don't leave the ice, and have you name and address on them, how is that different from any other 'signalling device'. For what it is worth, I have seen guys use basically the same rig, just smaller bottles and cans for perch.......
