The Dodge W200 high beam headlight uses H6024 or H4651 bulb size, while low beam headlight uses H6024, H4656, or H4652 bulb size. The replacement chart covers 1975 to 1980 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 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards applicable in both the US and Canada. Because it is a sealed beam, the entire unit is replaced rather than an internal filament or bulb element.
The H6024 serves as both the high beam and low beam headlight across the Dodge W200 for the 1975-1978 model years, as well as for 1979-1980 two-headlamp configurations. A single sealed beam type therefore handles both functions in those applications.
The H4651, H4652, and H4656 are all 4x6-inch rectangular sealed beam units operating at 12V under ANSI standards. Like the H6024, none of these units accept a replaceable internal bulb; the entire sealed assembly is the serviceable component.
The H4652 is documented as a variant of the H4651. Although both are 4x6-inch rectangular sealed beam units, they carry distinct part designations and are not listed as interchangeable within the specifications.
For the Dodge W200 in 1979 and 1980, the four-headlamp configuration separates high beam and low beam functions into different sealed beam types. The H4651 handles the high beam role while the H4656 (1980) and H4652 (1979) handle the low beam role.
The 1979 and 1980 model years each present two distinct fitment paths depending on whether the vehicle carries a two-headlamp or four-headlamp system. Selecting the wrong sealed beam type for the installed headlamp count results in an incorrect fitment.
The rectangular sealed beam units (H4651, H4652, H4656) appear exclusively in the 1979-1980 four-headlamp configurations. The round H6024 unit covers all remaining applications across the 1975-1980 range.
All sealed beam types listed across the W200 specifications operate at 12V, which is consistent with standard 12-volt automotive electrical systems used in passenger and light commercial vehicles of that era.
