The Dodge B200 headlight bulb specifications include H6024 and H4651 sizes for high beam operation, along with H4656 for low beam functions in this particular bulb size configuration. The replacement chart covers 1971 through 1980 production years with corresponding bulb size data.
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 headlight unit across the Dodge B200 specification range, serving as both the high beam and low beam source in the two-headlamp configuration from 1971-1980 and as the sole headlight unit from 1971-1978.
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 B200 for 1979 and 1980 was available with either a two-headlamp or four-headlamp system, and the correct bulb sizes differ between these two configurations, making the headlamp count a critical factor in selecting the proper replacement unit.
In the four-headlamp configuration for 1979-1980, the high beam and low beam functions are handled by separate units: the H4651 serves the high beam position and the H4656 serves the low beam position.
The H4651 and H4656 are both 4x6-inch rectangular sealed beam units operating at 12V under ANSI standards. Despite sharing the same physical format and voltage, they are not interchangeable with each other, as each is rated for a distinct beam function.
Neither the H4651 nor the H4656 is interchangeable with the H6024, as the rectangular 4x6-inch form factor of the former two units is physically incompatible with the 7-inch round format of the latter.
