Its something to do with the headlamps so they are not on full without the ignition on, some 80 regulation in a far away country

Yes the old 'dim dip' system that was required for a few years in the UK, then faded out (no pun intended) About 1987 up to 1991/2 i think.

The heat sink fins on the side are probably for dropping the alternator output to 10 volts so that the dip filament glows a sort of tangerine colour when the engine is running and the sidelights are on. Make sure it's mounted somewhere where the heat can get away.

unplug it & throw it in a canal

may aswell leave it alone- took it away in the dash somewhere, but as guderian says room for the heat to escape is needed.
