Ford F-250 Headlight Bulb Size

Additional Notes

• The 9007 bulb is the most widely specified type across the Ford F-250 headlight data, covering both high and low beam positions from 1992-1999 (with the exception of 1999 halogen capsule headlamp variants sharing the same designation). It is a dual-filament halogen bulb with a PX29t base, rated at 12V with 65W on high beam and 55W on low beam, conforming to the ANSI standard for the US and Canadian markets.
• The 9004 bulb serves both high and low beam functions on the F-250 for 1987-1991. Like the 9007, it is a dual-filament halogen type operating at 12V, but it carries a lower wattage rating of 65W/45W and uses a P29t base rather than the PX29t base found on the 9007. The two bulb types are not interchangeable despite their similar appearance and function.
• The H6024 is a 7-inch round sealed beam unit conforming to the ANSI standard. Because the lens, reflector, and filament are fused into a single assembly, the entire unit is replaced rather than an internal bulb. It is specified for both high and low beam positions on the F-250 across a broad span of model years.
• The H6054 is a 5x7-inch rectangular sealed beam unit, also an ANSI-standard whole-unit replacement type rated at 12V. It is specified for the F-250 from 1980-1986 and again as an option for 1999 models equipped with sealed beam headlamps, where it covers both high and low beam positions.
• For the 1999 Ford F-250, two distinct headlamp system configurations are documented: halogen capsule headlamps using the 9007 bulb and sealed beam headlamps using the H6054 unit. These configurations are not interchangeable, and the correct bulb type depends on which headlamp system the vehicle carries.
• The 1978-1979 model years carry two separate fitment entries depending on headlamp configuration. Vehicles with two rectangular headlamps use the H6054 sealed beam unit, while those with two round headlamps use the H6024 unit. Selecting the wrong sealed beam type for the housing configuration would result in an improper fit.
• The H6006 is a 5x7-inch rectangular sealed beam unit specified for the F-250 for 1953-1955 across both high and low beam positions. Although it shares the same physical format as the H6054, the two are distinct ANSI part numbers and are not listed as interchangeable within these specifications.
• The 1958-1960 model years show a split between high and low beam sealed beam types: the H5001, a 4-inch square unit, is listed for the high beam position, while the H5006, a 5.75-inch round unit, is listed for the low beam position. Both are whole-unit sealed beam replacements operating at 12V.
