A set of bulbs would be difficult for my car, as it has no user changeable bulbs.

That doesn't sound very helpful, but is the way maintenance seems to be going these days.

The headlights use dangerously high voltages and everything
else uses LEDs, which not only have a much longer life
expectancy, they also have multiple redundancy.

but, what usually fails is the electronics driving the LEDs, rather
than the LEDs themselves.

In which case a spare set of bulbs wont help you.
