Guy,
The headlight switch does not need to be grounded.

I think you are probably looking at a bad connection or a broken wire, that=
 makes contact when you hold the housing a certain way, then opens up when =
you hold it a different way.  Could be inside the switch, could be one of t=
he wires in the column.

As an EE friend of mine used to say, a test is worth a thousand theories.  =
Probe the red with green wire with a suitably grounded test light, at the s=
witch, then move things around until the lights go out.  If the test light =
stays lit, the problem is between where it is connected and the lights.  Ot=
herwise the switch is bad.  (It=E2=80=99s quite possible for one switch con=
tact to fail or become intermittent while the others still work).

Accidentally, I jostled the bell-shaped upper part of the steering column t=
o which the switches are secured, and they came on!
On closer inspection, that bell-shaped part is separate of the main steerin=
g column, and had become loose.
I manipulated that bell section and the parking lights would come on, or go=
 off, depending on what I was doing.
