Yes, the resistance of a tungsten filament lamp does increase with
temperature. It's lowest when the lamp is off.

that

Yes. Your problem is elsewhere, probably one of the many
marker lights. Pull all four corners, and check the license
plate lamp
I've been driving around for a couple of months with the instrument cluster
pulled out a bit (maybe 1/2 away from being fully seated) -- need to to
pull it completely out out and repair the odometer. It was such a pain to
remove when I installed new dash lights that I didn't push it back all the

Fuse #3 pops when the headlight switch is in the first stop left (3)

both impact

This will pass current and not burn something up in the process?
Yes, that's the point. A 10W lamp will be less than 1A of
current, hard to burn up any automotive type wiring with
only one amp. Where else are you going to find a 10W power
resistor with built-in visual indication as cheap?
A handy use for a dead porcelain MB fuse body is as a
carrier for electrodes to a test lamp.

I doubt it -- which is why I don't think that part of the circuit is
involved.
I am going to have to print out the wiring diagram and start tracing stuff.

Yeah - eliminate systems, somehow.

I've done that already, with the exception of the headlight wipers.

Different chassis here (W123) - but we had similar issue that was at

I should add this -- the problem suddenly appeared. We took the car to Omaha
