Thanks so much for all of the help, comments and great explanations as
to what was going on with my tail lights! You all rock! I clean all
of the connections and scraped just a bit of paint, added star
washers, tighten it all back up and you know it, the lights work great!
Thanks again for all of the help, I really appreciate it.
Rob

Hi,
I have a 67 bug with a problem tail light.
It is the right hand side and here is what is happening;
Press brakes = light works, but is not as bright as the left side
Headlights on = all is good
Headlights on and press brakes = light goes out
Both rear turn signals work fine.
I have checked and replaced the bulbs with no change.
Any ideas?
Thanks,
Rob Garretson ?

Check the ground wires and connections.

Sounds like a bad ground. If I recall correctly the taillight grounds
to the body, does not have a separate ground wire back there. Clean
the area where the housing touches the body and re-tighten the screw.

There's supposed to be star washers under the nuts that attach the
housing to the fender - these cut through the paint to make contact. If
the problem just started, you want to clean the washer and nut on each
stud, and reinstall - a little anti-seize wouldn't hurt on the studs. If
the problem has been there all along, you might want to look at the
fender bolts. If someone did a real good job painting the underside of
the fenders before installing them, you might not have a good connection
from the body to the fender. At least one of the fender bolts ought to
cut through the paint to make a connection.
The sheet metal screw that attaches the reflector to the housing is also
a ground, and should be clean.
If all else fails, a grounding wire from one of the taillight mounting
studs to a fender bolt might be needed.
I think it was 1968 models that started running ground wires in the
harnesses, instead of relying on the bodywork.

I agree with the bad ground diagnosis. The early VWs used a lot of
grounding
via screws in the metal body panels. Even my 8n Ford tractor grounds
through the body work and I absolutely detest this. I run seperate
ground
wires on everything or at least to a solid terminal lug on something
substantial. I no longer have any grounding issues.

Bad ground.
What is happening is that the brake light circuit is trying to use the
hot side of the parking light circuit as a ground instead of the sheet
metal of the car. With the parking AND brake filaments lit, you've
got 12V from the former running head-on into 12V from the latter.
Like two matching forces pushing directly against each other, the
result is zero volts, which is why the bulb goes out. With the park
lights off, the brake light can no longer use it as a path to ground
and must use the obviously degraded (ie: corroded) factory ground that
you have -- which is why it is so dim.
A better analogy would be a tee intersection, with two cars (one being
the power from the brake circuit and one for the park circuit) moving
directly towards each other, and the tee (the ground path) much too
heavily congested for both cars to use simultaneously. Take out the
second car and there's just enough room for one of the cars to turn
down the side, but not without a lot of scraping (resistance) going on.

You do realize that you just described the alternator/generator light
circuit right? Only in that case it's intentional.

This sounds pretty classic for a bad ground.
Check the grounding on that light, clean up the
ground jumper (or put one on if it isn't there)
and clean up the socket. Should work.

Yup, but I've been wanting to use that "tee intersection" analogy for,
like,
forever!
