My Son (18 last June) is now the main driver of my Vanagon.  He woirks
the graveyard shift at a local grocery store restorcking the shelves.
When he gets home just after 7 a.m. in the morning, he turns the van
off, sees that the headlights go off, and goes to bed.  Of course, the
parking lights are still on.  Unlike more contemporary vehicles, there
is no buzzer that goes off when the key is removed and the lights are
still on.  How do I rig up something that sounds a buzzer when the
lights are on, but the engine is off?

Thank you,

John
