The Nissan 240Z uses a 97 bulb size for both front and rear side marker applications. The replacement chart covers 1970 to 1973 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 Nissan 240Z uses the 97 bulb for both front and rear side marker positions across all model years covered in the specifications, spanning 1970-1973.
The 97 is an ANSI-standardized bulb recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical standards shared across those markets.
It operates on a 12-volt system and draws 13 watts, which places it in the low-wattage range typical of marker and auxiliary lighting applications.
The 97 uses a BA15s bayonet base, a single-contact fitting where the bulb is inserted and rotated to lock into place, as opposed to a screw or wedge-type base.
As a single-filament bulb, the 97 serves only one lighting function per socket, distinguishing it from dual-filament types used in applications requiring both running and stop light output from a single unit.
The 97 is described as a variant of the 1156 bulb. While the two share the BA15s base type, they are not the same bulb, and the 1156 operates at a higher wattage of approximately 26.9 watts, making direct substitution a consideration that warrants attention to the specific socket and circuit requirements of the Nissan 240Z.
