The Dodge D200 headlight bulb sizes include H6024 and H4651 for high beam applications, with low beam configurations utilizing H6024, H4656, and H4652 bulb sizes. The replacement chart covers 1975 through 1980 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 H6024 is the dominant bulb type across the Dodge D200 specifications, appearing in both high beam and low beam positions for the 1975-1978 model years without condition, and also serving the two-headlamp configuration in 1979 and 1980.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards recognized in both the United States and Canada. As a sealed beam, the entire unit is replaced rather than an internal filament or capsule.
The Dodge D200 for 1979 and 1980 introduced a four-headlamp configuration alongside the two-headlamp setup, which required a different set of rectangular sealed beam units rather than the round H6024.
The H4651 and H4656 are 4x6-inch rectangular sealed beam units, both operating at 12V under ANSI standards. The H4651 serves the high beam position in the four-headlamp configuration, while the H4656 fills the low beam position for the same setup in 1980.
The H4652, used in the low beam position of the four-headlamp configuration for 1979, is a variant of the H4651 and shares the same 4x6-inch rectangular sealed beam format at 12V.
Because the H4651 and H4652 are distinct part numbers despite their physical similarities, substituting one for the other in a four-headlamp system would not be consistent with the listed specifications.
All four bulb types in these specifications are sealed beam units, meaning none of them accept a replaceable internal bulb. Servicing any headlamp position on the D200 involves replacing the entire sealed lens-and-reflector assembly.
The two-headlamp and four-headlamp configurations for 1979 and 1980 are not interchangeable in terms of bulb fitment, as the round H6024 and the rectangular H4651, H4652, and H4656 units occupy physically incompatible housings.
