I’ve removed the rear indicators a few months ago to do the tail tidy and neaten’ up the back end a bit. I got half way through the job and it’s been like that through most of the winter... does it matter which wire goes to which contact on the indicators as by now I’ve completely forgot
No, it's not polarity sensitive, if you later wanted to fit LED bulbs you would have to change it if it was wrong. It's just an filament that heats up.
