Let me think - the reset button can only work when the light is powered up (and maybe too hot to touch) - you can't mount it on the metal base because that's live when it's on, and so the light fitting is designed so you can't touch the base. you could mount it in the glass but it would cast a shadow ... any solution has to cost less than a penny ...

> Let me think - the reset button can only work when the light is powered up (and maybe too hot to touch) A capacitor that is kept charged during normal operation, and that powers the reset circuit which you close with your metal pin once you unscrew the bulb. The circuit flips some bits in persistent memory of the bulb.

  So it resets every time you leave the bulb off long enough for the capacitor to discharge?

    No. "Reset" is done by a circuit, and the only way to power it is by connecting that capacitor to it by pushing something into the reset pinhole. If you don't do that, capacitor eventually discharges but since the circuit never gets powered, no reset happens. So after a while you need to connect the bulb to mains power in order to be able to perform reset.

Most LED’s have a wide bit between the electric bit and the glass. Having that live would be a significant safety risk which I doubt major companies would risk. https://www.homedepot.com/p/Philips-75-Watt-Equivalent-A19-Non-Dimmable-Energy-Saving-LED-Light-Bulb-Daylight-5000K-2-Pack-463000/206923058 https://www.homedepot.com/p/Philips-75-Watt-Equivalent-A19-N... It’s a heat sink that gets hot to to the touch, though not that quickly as your talking ~10w of waste heat. Sill several ways to do a reset switch just after power is off.
