The Dodge W100 uses H6054 and H6024 bulb sizes for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1975 to 1989 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The two bulb types specified across all listed model years for the Dodge W100 are the H6054 and the H6024, both of which are ANSI-standard sealed beam units recognized in the United States and Canada.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The H6024 is a 7-inch round sealed beam unit, also operating at 12V and sharing the same sealed beam construction that requires full unit replacement.
Both the high beam and low beam positions on the Dodge W100 use the same bulb size for any given model year, meaning a single bulb type serves both functions across the two-headlamp system.
For the 1985 model year, the correct bulb size depends on headlamp configuration. Vehicles equipped with 2 rectangular headlamps take the H6054, while those equipped with 2 round headlamps take the H6024. These two types are not interchangeable due to their differing shapes and housing designs.
The H6054 rectangular unit is specified for model years 1984 and 1986-1989, while the H6024 round unit is specified for model years 1975-1977.
Because sealed beam units integrate the lens, reflector, and filament into a single sealed assembly, substituting one sealed beam type for another requires a compatible headlamp housing, as the physical form factor differs between round and rectangular units.
The 12V operating voltage of both the H6054 and H6024 is consistent with standard 12-volt automotive electrical systems used in production vehicles of this era.
