Nissan 300ZX Headlight Bulb Size

Additional Notes

• The Nissan 300ZX used three distinct headlight technologies across its 1984-1996 production span: the H6054 sealed beam unit, the dual-filament 9004 halogen bulb, and the separate single-filament 9005 and 9006 halogen bulbs for high and low beam functions respectively.
• The 1984-1986 300ZX used the H6054, a 5x7-inch rectangular sealed beam unit operating at 12V. Unlike conventional bulbs, the H6054 is not a replaceable bulb within a housing; the entire sealed unit is replaced as one assembly.
• The 1987-1989 300ZX used the 9004 for both high and low beam functions. The 9004 is a dual-filament halogen bulb with a P29t base, rated at 12V with separate wattage ratings of 65W for high beam and 45W for low beam within the same bulb.
• From 1990-1996, the 300ZX transitioned to a split-bulb system, with the 9005 handling high beam duties and the 9006 handling low beam duties as two physically separate bulbs.
• The 9005 is a single-filament halogen bulb with a P20d base, rated at 12V and 65W. The 9006 is also a single-filament halogen bulb but carries a P22d base and a lower wattage rating of 55W, reflecting its dedicated low beam role.
• The P20d base of the 9005 and the P22d base of the 9006 are not interchangeable. Although both are single-filament bulbs operating at 12V, their base configurations differ, preventing cross-fitment between the two positions.
• All bulb types listed for the 300ZX conform to ANSI standards applicable in the United States and Canada, meaning each type adheres to standardized electrical and physical specifications within those markets.
• The 9004 dual-filament design used in 1987-1989 consolidates both beam functions into a single socket, whereas the 1990-1996 system requires two separate sockets per headlight assembly, one for each beam function.
