The INFINITI J30 high beam headlight uses a 9005 bulb size while the low beam headlight requires a 9006 bulb size. Replacement bulb specifications in the chart cover vehicle production from 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 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across all model years from 1993-1997.
Both the 9005 and 9006 are ANSI-standardized halogen bulbs recognized in the United States and Canada, meaning they conform to a defined set of performance and dimensional requirements rather than being proprietary to any single manufacturer.
The 9005 is a single-filament halogen bulb operating at 12 volts and 65 watts, fitted with a P20d base, and serves the high beam function on the J30.
The 9006 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a P22d base, and serves the low beam function on the J30.
Although the 9005 and 9006 share the same voltage rating and a visually similar form, their base types differ: the 9005 uses a P20d base while the 9006 uses a P22d base, making the two bulbs physically non-interchangeable in their intended sockets.
The wattage difference between the two bulbs reflects their respective roles: the higher-wattage 9005 at 65W produces greater light output suited to high beam use, while the 9006 at 55W is calibrated for the controlled beam pattern required at low beam.
