Incorrect Replacement Knob 

Purchasing a 1947-1955 optional cigarette lighter assembly from many vendors provides you a reproduction that is far from correct. It appears an overseas manufacturer decided to offer a lighter assembly made with the currently available 12 volt base and joining it to a 1947-1953 headlight knob.

Thus, no tooling investment and all parts were already available.

Check the following images. What a difference! There is nothing rare about the original knob. Just replace the new for the correct original.

Original Note: In the future, the correct lighter base and knob will be produced by Jim Carter Truck Parts. Stay tuned.
