The Nissan 280Z uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1975 to 1978 model 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-standardized sealed beam unit used in both the high beam and low beam headlight positions of the Nissan 280Z across the 1975-1978 model years.
As a sealed beam unit, the H6024 integrates the filament, reflector, and lens into a single non-serviceable assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H6024 is a 7-inch round format operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada.
Because the Nissan 280Z uses the same H6024 unit for both high and low beam functions across all four model years covered, the two positions are served by physically identical assemblies.
The ANSI standardization of the H6024 means the unit is defined by a regulated specification rather than a proprietary design, which historically allowed interchangeability across different vehicle makes that shared the same sealed beam format.
