Volkswagen 412 headlight bulbs utilize the H6024 size for both high beam and low beam functions. The replacement chart covers 1973 to 1974 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is the sole bulb type listed across all headlight positions for the Volkswagen 412, covering both 1973 and 1974 model years.
The H6024 is an ANSI-standard sealed beam unit used in the United States and Canada. It operates at 12 volts and is constructed as a 7-inch round assembly.
As a sealed beam unit, the H6024 does not contain a replaceable bulb element. When the unit fails or is damaged, the entire assembly requires replacement rather than an internal bulb swap.
The H6024 serves both the high beam and low beam headlight positions on the Volkswagen 412 for 1973-1974, meaning a single unit type covers all primary forward lighting functions.
The 7-inch round format of the H6024 is a standardized size in North American automotive lighting, which historically allowed interchangeability across many vehicles using the same sealed beam specification.
Because the H6024 is an ANSI-standardized sealed beam, its physical and electrical characteristics are governed by a defined industry standard rather than being proprietary to a specific manufacturer or vehicle.
