1947-1953 Chevy Truck Rubber Tail Light Wire Covers.  Check out these nice pliable, rubber wire jackets. They are about 1/2" OD, 5/16" ID and 23" long. The tail light end is about 9/16" ID. The listing is for a pair. Isn't it time to hide that ugly wiring? I am constantly adding new Tail Light assemblies to my ClassicCarGoodies Store. I might have just what you're looking for!
