First AD I had, back in '70, had the signals on the fenders and my current '53 1 ton has them. One thing that I have noticed about daily driving an AD, especially a big panel truck is that people sometimes are so focused on "that old truck" they don't seem to really see what the truck is doing, even when there isn't a cellphone in the picture.
I have come to believe that it is hard to have bright enough and visible enough signal lights. I know that the fender mounted lights look goofy to some, but oncoming drivers really seem to see them when they're flashing. They are also really visible to any cars on the sides when you are turning or changing lanes. To each his/her own. Don
