Additional Notes

The H6054 is the most widely used headlight unit across the Dodge W150 specifications, appearing in both high beam and low beam positions for the 1981-1993 model years, as well as the 1982-1984 range. It is an ANSI-standard 5x7-inch rectangular sealed beam unit rated at 12V, and the entire unit is replaced rather than an internal bulb.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards for the US and Canada. It serves both high beam and low beam functions on the W150 for the 1977-1979 model years, and also applies to 1980 two-headlamp configurations.
The 1985 Dodge W150 requires different units depending on headlamp configuration. Vehicles equipped with two rectangular headlamps use the H6054, while those equipped with two round headlamps use the H6024.
The 1979 and 1980 model years each present two distinct fitment paths based on headlamp count. Two-headlamp configurations use the H6024, while four-headlamp configurations use the H4651 for high beam and the H4652 for low beam.
The H4651 and H4652 are both ANSI-standard 4x6-inch rectangular sealed beam units rated at 12V. They are variants of each other, with the H4651 designated for the high beam position and the H4652 for the low beam position in four-headlamp configurations.
All four bulb types covered in these specifications are sealed beam units. None contain a replaceable internal bulb; the entire sealed assembly is the serviceable component.
The H6054 and H6024 units share the same 12V rating and ANSI compliance, but differ in form factor. The H6054 is rectangular at 5x7 inches, while the H6024 is a 7-inch round unit, making the two types physically non-interchangeable despite their shared electrical standard.
The H4651 and H4652 share the same 4x6-inch rectangular form factor and 12V rating, yet they are not interchangeable between beam positions, as each is specified for a distinct function within the four-headlamp system used on the 1979-1980 W150.
