Nissan Maxima Headlight Bulb Size

Additional Notes

• The 9004 bulb is the most frequently specified type across the Nissan Maxima headlight data, appearing in both high beam and low beam positions for model years 1985-1999. The 9004 is a dual-filament halogen bulb that handles both high and low beam functions within a single housing, operating at 12 volts with filaments rated at 65 watts (high) and 45 watts (low).
• The D2S and D2R bulbs are High-Intensity Discharge (HID) types that appear across multiple model years in the specifications. D2S bulbs use a projector-style housing with a sharp cutoff shield inside the bulb itself, while D2R bulbs are designed for reflector housings and have an internal shield to control light distribution. These two types are not interchangeable despite sharing the same electrical base and arc tube design.
• The Nissan Maxima (2004-2007) with halogen capsule headlamps uses the 9012 bulb for both high and low beam positions. The 9012 is functionally similar to the 9006 but operates without a tab that would otherwise prevent installation in 9006 sockets, making physical fitment a critical consideration when sourcing a replacement.
• For the 2019 Nissan Maxima built up to November 2018, the high beam position specifies a 9003 bulb. The 9003 is a dual-filament bulb equivalent to the European H4 standard, producing 60 watts on high beam and 55 watts on low beam. This production date condition means two different high beam bulb types exist within the same model year.
• The H9 bulb is specified for the high beam position in model years 2016-2018. H9 is a single-filament halogen bulb rated at 65 watts, belonging to the PGJ19 base family. It is physically similar to the H11 but operates at a higher wattage, and the two are not directly interchangeable without modification due to tab differences on the base.
• Model years 2009-2014 with halogen capsule headlamps use the H11 bulb for the low beam position. The H11 is a single-filament halogen bulb rated at 55 watts with an L-shaped base, and it is among the most widely used low beam bulbs in the automotive industry during that period.
• The 2008 Maxima with halogen capsule headlamps specifies the 9005 for both high and low beam positions, while the 2007-2004 halogen variants use the 9012 for both positions. These two bulb types are not interchangeable, and the distinction between these adjacent model years is a relevant fitment consideration.
• The H4651 and H4656/H4652 sealed beam bulbs appear in the 1981-1984 model years for high and low beam positions respectively. Sealed beam units are self-contained lamps where the reflector, lens, and filament form a single sealed unit, unlike the replaceable capsule bulbs used in later years. H4651 and H4651R are rectangular sealed beam types, while H4652 and H4656 are also rectangular but differ in filament configuration and light output.
• The 2002-2003 low beam position is the only range in the specifications where the D2R bulb appears. All other HID-equipped model years across both high and low beam positions use the D2S type. Substituting D2S for D2R or vice versa in a given housing produces incorrect light distribution and potential glare for oncoming traffic.
• The 9003 bulb serves as both the high beam and low beam bulb for model years 2000-2001 and the 2019 model year, reflecting its dual-filament design. In contrast, model years using separate H9 (high) and H11 (low) bulbs require two distinct single-filament bulbs to cover both functions, meaning the headlight assembly in those years uses dedicated housings for each beam.
