Spark plug answer

Content Tools

In reply to the question about the spark plug by Verlin Wendt, The plug is a Beacon-Lite, manufactured by the Beacon Spark Plug Corp. of North Tonawanda, N.Y., in the 1920s. The 1/2-inch pipe thread was most commonly used in the Ford Model T and early Fordson tractors. It was also widely used by other early gas engine and tractor builders, and less commonly used in other early automobiles. The idea of the Beacon-Lite was that it flashed as the cylinder fired, thus indicating a working ignition.

Those interested in early spark plugs are invited to join the Spark Plug Collectors of America, an international organization founded in 1975. We publish a 38-page quarterly magazine called The Ignitor. Most people would be surprised to learn there were over 6,000 different spark plug makes in the U.S. alone.
