Sorry, this isn't on my Vanagon, but on my Golf.  But since I'm sure
they're wired the same, it may help someone with their Vanagon =)

I put Euro-spec Hella Golf IV style lights in my 98 Golf III.  I took
them apart and painted the surrounds, and turned the marker or city
light position into a signal light, and drilled the reflector and moved
the city light there.  I put 5W (?) signal light bulbs in the old marker
position (required some clearancing) as a signal light.  Now for the
problem...  I wired my city lights to a constant power so they are on
whenever the ignition is on.  I am running the signal light off the
previous signal light circuit.  The old running light circuit is unused
in the front.  When my headlights are off, everything works
tickety-boo.  But when I turn my headlights on, my signal lights blink
double time.  Now, I assume that the car is sensing that the marker
lights is missing (well, it thinks it's just burnt out).

My question - does anyone know a way around this?  Can I put a resistor
in the circuit to take the place of the marker light (and if so, how
big?).  The only other way I can really see is to re-connect the
original dual filament bulb and hide it behind the bumper or something,
but I'd rather not.

Cheers!
