The Nissan 260Z uses H6024 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1974 to 1975 model 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 Nissan 260Z, covering both the high beam and low beam functions for the 1974-1975 model years.
The H6024 is a 7-inch round sealed beam unit operating at 12 volts. It conforms to ANSI standards applicable in the United States and Canada.
A sealed beam unit integrates the filament, reflector, and lens into a single fused glass assembly. Because of this construction, the H6024 is replaced as a whole unit rather than as an individual bulb.
The H6024 serves dual duty in the 260Z, covering both high beam and low beam headlight positions. This means a single part number applies to all four headlight sockets on the vehicle.
The shared fitment of the H6024 across both beam functions is a characteristic of the sealed beam era, during which a single standardized unit could be wired to perform either function depending on its circuit connection.
The ANSI standardization of the H6024 means the unit conforms to a regulated physical and electrical specification, which historically allowed interchangeability across different vehicle makes that used the same 7-inch round format.
