Nissan Frontier headlight bulbs use 9007 and 9004 sizes for both high and low beam applications. The replacement bulb size chart covers 1998 to 2023 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9007 bulb is the dominant headlight type across the Nissan Frontier's specification range, covering both high beam and low beam functions for the 2001-2019 and 2023 model years.
Both the 9007 and 9004 are ANSI-standardized dual-filament halogen bulbs operating on a 12V electrical system, meaning a single bulb unit serves both the high and low beam functions within one housing.
The 9007 bulb operates at 65W on the high beam filament and 55W on the low beam filament, using a PX29t base.
The 9004 bulb operates at 65W on the high beam filament and 45W on the low beam filament, using a P29t base.
Although the 9007 and 9004 share the same high beam wattage of 65W, their low beam wattages differ by 10W, and their base types are not the same, making the two bulbs physically non-interchangeable despite their similar appearance.
The Nissan Frontier (1998-2000) uses the 9004 bulb for both high and low beam headlights, while the 2001 model year marks a transition to the 9007 specification that carries forward through subsequent years.
Because the 9004 and 9007 use different base configurations, a 9004 bulb cannot be installed in a socket designed for a 9007, and vice versa, without modification.
The ANSI standardization of both bulb types means they are produced by multiple manufacturers to a consistent specification, with the same rated voltage and wattage values expected across all compliant units.
