...most likely a "marker light" (but maybe an add on turn signal) and looks identical to the newer AD series 1947 GMC's marker light design. ...If you zoom in on your pic, I can also see where the earlier style 1941-46 "marker lights" that where designed/mounted on top of the headlight pods seemed to have been on your truck. ... The fender mounted fixture could be an add on, or maybe another mid year switch over thing as they were gearing up for the new 1947 AD series truck style???
Hard to say. I see other people have the headlight mounted market lights. I also see that later model 1947's have the fender marker light. I can say, mine seem original - but hard to say.
My truck is an EC - whereas your manual says CC. I wonder if that is the difference.
It seems turn signals didn't exist (well... your hand existed, but you know what I'm saying). Mine does have an after-market turn signal assembly on the steering column. But the previous owner hacked it up something terrible.
Thanks for the info.
