Horn relays

[quk@isham-research.demon.co.uk (Phil Payne)]

Many years ago I drove a Mercedes 600 with a three-position horn
selector.  One position was for discretely attracting the attention of
valet parkers and could not be heard more than three car lengths away,
one was a normal street type, and one was for trying to wake up ovloV
drivers on Autobahns.

Perhaps some friendly electronics expert (Orin?) could come up with an
automatic version, keying off the roadwheel movement signal sent to the
ISV?  This would switch the 'discrete' relay below, say, 5mph - the
normal one from 5mph to 50mph, and the "you lunatic" one above that.

It would perhaps also go up through the relays if the horn button were
kept depressed ...
