So, sorry for posting such a silly question, but my Golf mk2 is parked remotely, and I brought home the handbrake instrumental light w/bulb holder. I mistakenly binned the working bulbholder behind a scratched red facade, together with the broken dashboard/instrument surround, when changing to unbroken/good condition parts. So, planning to replace the 4mm bulb with a 3mm LED, thus I need to know the polarization on the bulb holder. Can anyone confirm which lead (+ or -) is put on the side of the bulb holder, where the connector clip is located?
