Porsche 930 high beam and low beam headlight bulbs both utilize the H6024 bulb size. The replacement chart covers 1978 to 1979 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 Porsche 930, covering both the 1978-1979 model years.
The H6024 is an ANSI-standardized sealed beam unit, meaning the lens, reflector, and filament are fused into a single glass assembly. When the filament fails, the entire unit is replaced rather than an internal bulb.
The H6024 follows a 7-inch round form factor, which was a regulated standard in North America that allowed sealed beam units from different manufacturers to be interchangeable across vehicles of the same specification.
The H6024 operates at 12 volts, consistent with the standard electrical system voltage found in passenger vehicles of that era.
The H6024 carries ANSI standardization applicable to the United States and Canada, meaning its physical and electrical characteristics are governed by a defined North American specification rather than a manufacturer-specific design.
Both the high beam and low beam positions on the Porsche 930 share the same H6024 specification for 1978-1979, indicating the vehicle used separate sealed beam units for each function rather than a single dual-filament assembly per side.
