The '41 thru '46 Art Deco series trucks are often found with those stupid big round turn signals perched on the fenders.. some got put between the headlight and the hood.. others got put on the road side of the headlight bucket (extra ugly, IMO)
I've left 'em on my '46 just because I don't want to hassle with patching the holes in the fenders, and the design of the Art Deco trucks dosen't make the aftermarket turn signals stick out quite so stupid looking.. but on Advance Design trucks, they really look silly.. especially the 1/2 and 3/4 ton trucks.
