(OP)
There was a question here a year or so ago. It was about opening and closing a flap (waste gate?) in a car. I sketched a solution that, in my view, was simple and reliable. The OP came back and said it worked well.
I made a small application note and sent it to the "Idea for Design" department in the Electronic Design paper. Their criteria for acceptance says: "Non trivial and not too simple" - I thought that a simple incandescent lamp was too simple. It is, after all, the simplest circuit there is in starter kits like "The Little Electrician".
I forgot about it and was very surprised when I got mail from a guy named Lliam where he thanked me for the solution to a problem he had. Nice and surprising. Maybe it wasn't so simple after all?

I guess for this application, any effects on the open/closing time are not that relevant? Depending on usage, that could create a slightly larger boost spike as the wastegate is being controlled.

My favorite lamp circuit from Electronic Design was an AC voltage regulator that used three resistors and a lamp in a bridge. We built a product that required a trip at 20mv either AD or DC. The rule there was never spend more than $20 on a test fixture. It didn't matter as to the engineers time. I remembered that circuit and the voltage out was rock solid form a power line of 90-135V. That is impressive for just a lamp. I fed the DC through the same circuit and switching from AC to DC produced the same voltage.
