I have restored a Rowenta E5291 heavy clothing iron, a remake of a vintage model, and I changed the pilot lamp's connection.
I made this change because this iron can never be turned off unless you unplug it so I modified the bimetal switch to allow it to be turned off when turning the button to the lowest setting. Everything worked good but it was still heating because the lamp was still directing the power to the heater so I have changed it in the following way:

But I am worried that it might blow up the lamp or trigger the breaker box. Since I strongly doubt I can find a replacement for the lamp, in case it gets busted, I would like to hear from anyone if this will work as I expect or if it will cause any problem.
Mind you that I am very amateur but I did check for continuity with a multimeter and everything looked good (Unplugged from the wall).

The modification will work but the sense of the indication changes entirely:
The voltage across the lamp when it is lit would be the same in either case, so the lamp should last as long as in the earlier mode.
