I often forget to turn off my electric soldering iron when I leave the workshop. Quite apart from the waste of power I am worried about the fire risk, so I have been looking for a plug fitted with an indicator light that would be visible when the overhead lights are turned off, but to my surprise I haven't been able to find anything. Does anybody know of a source for such a plug, or a way to adapt an ordinary plug? I thought of changing the sockets to the type with indicators, but that would entail changing all 16 double sockets, an expensive solution and one that wouldn't solve the problem as other equipment is left on overnight.
