Porsche 914 headlight bulbs utilize the H6024 size for both high beam and low beam applications. The replacement chart covers 1970 to 1976 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is an ANSI-standard sealed beam unit used in both the United States and Canada, operating at 12 volts with a 7-inch round form factor.
Unlike bulb-and-reflector assemblies, the H6024 is a sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The Porsche 914 uses the H6024 for both high beam and low beam headlight positions across all model years from 1970-1976, making it the sole headlight bulb type in these specifications.
Because both the high beam and low beam positions share the same H6024 specification, the 914 uses a dual-filament sealed beam design, where a single unit serves both lighting functions within one housing.
The 7-inch round sealed beam format was a regulated standard in North America during this era, which means H6024 units from different manufacturers were generally interchangeable as long as they met the same ANSI designation.
Substituting a non-ANSI-equivalent sealed beam unit in place of the H6024 would not conform to the specification, as the ANSI designation defines precise photometric and physical standards for the unit.
