If the main advantage was to allow forgetfulness with a reduced penalty,
a simple alarm to warn when the lights are left on would have been the
way to go. No factory wiring need be disturbed for such a device to
work.With the new headlight on law in California, I have been
considering just such a mod.

In Cali we must now also use our headlights whenever weather conditions
require our wipers to be on. Lots more chances to leave the lights on in
the daytime after parking.
