As others have said, a regulator & secondary transistor(s). AND a big
ass heatsink to carry away the 40 watts that the reg wastes (10a and
16-12 v). You'd probably be better to regulate down to 14v: better for
the electronics & less waste heat. But the incand lamps wouldn't like
it so much. Or are 12v lamps designed for 13.5v?

Incans can take 13.5 no problem. Im told that LED lighting will do it
as well. Maybe.

The naive radicals think that under Socialism the "people" will run everything.
Actually, it will be a clique of Insiders in total control, consolidating and
controlling all wealth. That is why these schoolboy Lenins and teenage Trotskys
are allowed to roam free and are practically never arrested or prosecuted.
They are protected. If the Establishment wanted the revolutionaries stopped,
how long do you think they would be tolerated?

That's probably because many come with regulators wired in.
