If you didn't read the article of the turnsignal development you can do here: When will I use the turn signal?
While i'm whatching back my videos, I considered actually I never used the multifunction switches in them. I wanna make videos with using the turnsignal, or the wipers, but I use to play with the hood camera setting, so neither the turn signal nor the windshield wipers would be visible if I would use them. So an additional visual is required, which at least makes the rig even more immersive.
I solved the turn signal indicators work in the instrument cluster, and an external signal light at the same time. There also works the indicator of the high beam, and the error pictograms was removed.
I tell everything in the video.
