Caution: reverse polarity!

Got the turn signals built today and then found that they do not work.
Now these things were but already bombproof and I almost scratched my paint, as I have ripped out with a string again. Unlike it was no longer holding really extreme.
Is in itself great, but not the following:

The turn signals are reverse polarity! It is hard to believe, but the connectors are assigned incorrectly. So I had to rewire my flasher cable to use turn signal lights can.
A Beipackzettelchen indicates that the cable "may" have to be replaced.

So just a tip from me: Before you make the turn signals permanently, check briefly whether they actually work. Otherwise, you really have to use force to get the flasher back out.

Otherwise they look chic and function.
