Greetings folks,

The headlights on my van have started playing up and I don't quite
understand what is happening.
When I turn them on both high and low beam are on.  When I turn OFF high
beam, low beam goes off ( I think that is the way, but it is hard to tell
which click would normally go to high and which normally go to low).  When I
turn off the ignition with the headlights on, the headlights stay on when
the parking lights would normally be all that is lit.

Has anyone experienced an issue like this?  Where should I look?  I'd
appreciate any wisdom people have.

Dave

PS I have NOT done anything to the wiring/lights in a couple of years.  This
is not a result of any fiddling having been done.
