Dodge Mini Ram high beam and low beam headlight bulbs utilize H6024, H4651, H4656, and H4652 sizes depending on configuration and model variation. The replacement chart covers 1984 through 1988 vehicle production 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 H6024, H4651, H4656, and H4652 bulbs used across the Dodge Mini Ram headlight system are all sealed beam units operating at 12V. In a sealed beam design, the lens, reflector, and filament are fused into a single unit, meaning the entire assembly requires replacement rather than an individual bulb.
The H6024 is a 7-inch round sealed beam unit conforming to ANSI standards recognized in both the United States and Canada. It appears in the 1987-1988 Mini Ram configurations equipped with a 2-headlamp system, serving as both the high beam and low beam unit in that setup.
The H4651 and H4656 are both 4x6-inch rectangular sealed beam units built to the same ANSI standard. The H4651 handles the high beam function, while the H4656 handles the low beam function in 4-headlamp configurations.
The H4652 is a 4x6-inch rectangular sealed beam unit and a variant of the H4651. It is specific to the low beam position in the 1987 4-headlamp configuration, distinguishing it from the H4656 used in that same role for 1984-1986 and 1988 models.
The Dodge Mini Ram headlight system across 1984-1988 is split between two distinct configurations: a 2-headlamp arrangement using the round H6024 unit and a 4-headlamp arrangement using the rectangular H4651 and H465x series units. These two configurations are not interchangeable, as they rely on physically different sealed beam formats.
For the 1984-1986 model years, only the 4-headlamp configuration is listed, with the H4651 assigned to high beam and the H4656 assigned to low beam throughout that range.
The 1987 low beam specification diverges from surrounding years in the 4-headlamp configuration, calling for the H4652 rather than the H4656 used in 1984-1986 and 1988. Despite the H4652 being a variant of the H4651, substituting one rectangular sealed beam unit for another without confirming the correct designation risks a mismatch in beam pattern or filament output.
