I have a 1950 4100. I konw it was stock without turn signals and only one tail light. when I got the truck the turn signals where already mounted on the fenders so Im not going to remove them. I have all the lights working,front and rear turns and parking stop lights. My question is can I get original equipment lights that have the daul fillement bulb? The one that came on the truck only works parking and stop lights not turn. I also might add it is still a 6 volt system which im not planning on changeing either.
