The Ford F-450 Super Duty high beam and low beam headlight bulb sizes include 9008, H6054, and 9007 configurations. A replacement chart documents bulb specifications across 1999 to 2022 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9008 is a dual-filament halogen bulb operating at 12V with a 65W high beam filament and a 55W low beam filament, fitted with a P26t base. Its dual-filament design allows a single bulb to serve both the high beam and low beam functions within one housing.
The 9007 shares the same 12V, 65W/55W dual-filament configuration as the 9008 but uses a PX29t base rather than a P26t base. Despite their identical wattage ratings, the two bulbs are not interchangeable due to this difference in base type.
The Ford F-450 Super Duty transitioned from the 9007 to the 9008 in halogen capsule headlamp applications between the 2004 and 2005 model years. Both bulbs carry the same ANSI standard designation for the US and Canada markets.
The H6054 is a 5x7-inch rectangular sealed beam unit rather than a replaceable capsule bulb. The entire unit is replaced as a single assembly, which is a fundamentally different service procedure compared to halogen capsule headlamp systems.
From 1999 through 2010, the F-450 Super Duty was available with either halogen capsule headlamps or sealed beam headlamps, making headlamp type a required consideration when selecting the correct bulb size for those model years.
From 2011 onward, the specifications list only the 9008 with no sealed beam alternative, indicating that the H6054 sealed beam option was no longer part of the headlamp configuration for those model years.
The 9008 serves as both the high beam and low beam bulb across all applicable model years in these specifications, a characteristic consistent with its dual-filament construction and a common arrangement in single-reflector headlamp assemblies.
All three bulb types listed, the 9008, 9007, and H6054, conform to ANSI standards recognized in both the United States and Canada, placing them within a standardized sizing and performance framework shared across many North American vehicle applications.
