Warpig - The light below the headlight in your pic was 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. The below pic from a 1947 GMC Maintenance Manual dated October 1947 shows the detail and looks identical to your fixtures. 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 other pic below is from a 1945 GMC Parts Book, detailing the exploded parts view of the 1941-46 headlight assemblies. 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???
