Nissan 240SX Headlight Bulb Size

The Nissan 240SX high beam headlight uses 9005 or H6054 bulb sizes, while low beam headlight applications require H1, 9003, or H6054 bulb sizes. The replacement chart covers 1989 to 1998 model years with corresponding bulb size specifications for each production year.

Additional Notes

The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. Unlike conventional replaceable bulbs, the entire assembly is the light source itself, meaning the whole unit requires replacement when it fails. The Nissan 240SX used this type for both high and low beam positions across the 1989-1994 model years.
The 9005 is a single-filament halogen bulb with a P20d base, rated at 12V and 65W. It follows the ANSI standard applicable in the US and Canada, and it served as the high beam bulb for the 240SX from 1995-1998.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 12V with 60W on the high beam filament and 55W on the low beam filament. As an ANSI-standard bulb, it was used exclusively in the low beam position on the 1995-1996 240SX, meaning a separate dedicated high beam bulb was also required for those years.
The H1 is a single-filament halogen bulb with a P14.5s base, rated at 12V and 55W. It follows the ECE standard used in Europe and worldwide, though it also carries approval for use in the US and Japan. The 240SX used it solely in the low beam position for the 1997-1998 model years.
The 1995-1996 240SX represents a transitional fitment configuration. The high beam position used the single-filament 9005, while the low beam used the dual-filament 9003. These two bulbs carry different base types, P20d and P43t respectively, and are not interchangeable with each other.
For the 1997-1998 Nissan 240SX, the high beam and low beam positions use two distinct bulb standards: the 9005 follows the ANSI standard while the H1 follows the ECE standard. Despite both being single-filament halogen bulbs at 12V, their base types differ and they cannot be substituted for one another.
The H6054 sealed beam units used through 1994 operate on a fundamentally different design principle than the socket-based halogen bulbs used from 1995 onward. Parts and installation methods for sealed beam assemblies are not compatible with the projector or reflector housings associated with replaceable-bulb configurations.
