The Dodge D250 headlight bulb uses H6054 and H6024 sizes for both high and low beam applications. The replacement chart covers 1981 to 1993 model years 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 H6054 is the dominant headlight unit across the Dodge D250 specification range, appearing in both high beam and low beam positions for the 1981-1993 model years, with one conditional exception in 1985.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada. 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 rated at 12V and built to the same ANSI standard. Like the H6054, it is a sealed beam assembly requiring full unit replacement.
For the 1985 Dodge D250, the correct headlight unit depends on the headlamp configuration of the vehicle. Units equipped with two rectangular headlamps use the H6054, while units equipped with two round headlamps use the H6024. These two part numbers are not interchangeable with each other.
Both the H6054 and H6024 serve dual-beam functions in this application. A single sealed beam unit handles both high and low beam output, which is why the same part number is listed under both the high beam and low beam sub-parts in the specifications.
The rectangular H6054 and the round H6024 differ in physical form and are not cross-compatible, meaning a vehicle configured for one headlamp shape cannot accept the unit designed for the other without modification to the housing.
