USB-C has firmly established itself as the universal connector standard, integrating data transfer, power delivery, and video output into a single interface.
Your solution may very well also work, good thinking. A few things to consider though:
- Putting capacitors in series requires balancing them
- A silicon full bridge rectifier drops ~1.4V frm the input
- Incandecent bulbs require a lot of current to get going, this may result in a delay for them to turn on
Interesting approach, never thought about using the cable for something completely unrelated.
Thanks, that's pretty much exactly what I found: https://en.wikipedia.org/wiki/USB_hardware#Allowable_current_draw
Pretty much what I expected, but I don't think they care to much about that
Where? I can't find any reference to any device being allowed to draw 10A: https://en.wikipedia.org/wiki/USB_hardware#Allowable_current_draw

The video dissects a USB-C cable marked with a 10A rating even though there is no such rating in the standard.
It would be interesting what this is meant for, as I've never seen a device with such a rating?
I've actually done that with a simple single diode rectifier and a supercap with zener voltage limitation:
If your supercap has a too low series resistance for the LED to light immediately you need an additional resistor in series with it. It is simple and small enough to directly fit inside the original lamp casing and has been working without a problem for over 3 years.
The USB-C standard and particularly the USB PD (power delivery) is so complex it almost feels comical.
The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc
This video tests three different cables, ranging from cheap to really expensive and explains the differences between each other
That's true, they explain this in a different video: https://www.youtube.com/watch?v=y9vXDy_zt4I

It indeed is, but there seem to be no testers available for resistance measurements.
