12V 30/30W. USA ''sealed beam'' style. Mandatory in the U.S. from 1939 to 1984; in either regular or halogen versions since it was forbidden to ride / drive any vehicle on a public road with replaceable light bulbs. In 1984 H-4 was finally approved and introduced. In the sealed beam the ''light bulb'' is sealed into the unit and cannot be removed. These are non EU approved period correct classics!
