Porsche bulbs are same as all German cars and are NOT "reverse polarity."

Center post is positive, side shell is negative.

At least for the tail lights, I believe you are incorrect for our cars. The center post is negative and the side is positive. That is why most LEDs won't work
The shell side is what is switched and the center is common.


I have no idea if other German cars are the same

You are 100% incorrect.

Our bulbs are reverse polarity. Center post is negative.

It's not the bulbs that are different, it's the bulb holder.

But yes, not much help ... sorry.

Incandescent bulbs don't have a polarity, but this thread is not discussing incandescent bulbs.
