The INFINITI J30 front turn signal uses a 1156NA bulb size while the rear turn signal requires a 1156 bulb size. The replacement chart covers vehicle production years spanning 1993 to 1997.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Infiniti J30 uses the 1156NA bulb for the front turn signal across all model years from 1993-1997.
The 1156NA is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base and natural amber glass.
The natural amber glass of the 1156NA produces an amber light output directly from the bulb itself, without relying on a colored lens to achieve the required turn signal color.
The rear turn signal on the J30 uses the 1156 bulb across all model years from 1993-1997.
The 1156 shares the same single-filament design, BA15s bayonet base, 12V rating, and 21W output as the 1156NA, differing only in the absence of amber-tinted glass.
Both the 1156NA and 1156 conform to ANSI standards applicable in the United States and Canada.
Because the 1156NA and 1156 share the same BA15s base and electrical ratings, they are physically interchangeable, though substituting a clear 1156 in place of the 1156NA at the front position may affect the amber color output if the housing lens is also clear.
The BA15s bayonet base designation indicates a single-contact base with a 15mm collar, a common format in automotive lighting that allows for tool-free bulb replacement.
