The Dodge W350 uses H6054 and H6024 bulb sizes for both high beam and low beam headlight applications. The replacement chart covers vehicle production spanning 1981 to 1993 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 H6054 is the dominant headlight unit across the Dodge W350 specification range, appearing in both high beam and low beam positions for the 1981-1993 model years, with one exception in 1985.
The H6054 is an ANSI-standardized 5x7-inch rectangular sealed beam unit rated at 12V. As a sealed beam design, the entire unit is replaced rather than an internal filament or capsule.
The H6024 is an ANSI-standardized 7-inch round sealed beam unit, also rated at 12V and also replaced as a complete unit. It serves both the high beam and low beam functions in a two-round-lamp headlight configuration.
The 1985 Dodge W350 is the only model year in these specifications where headlight configuration determines bulb size. Vehicles equipped with two rectangular headlamps use the H6054, while those equipped with two round headlamps use the H6024.
Because both the H6054 and H6024 are sealed beam units, they are not interchangeable with each other despite sharing the same voltage rating and ANSI classification system. Physical form factor governs fitment.
Both the H6054 and H6024 carry ANSI standardization recognized in the United States and Canada, meaning units from different manufacturers conforming to the same ANSI designation share identical optical and mounting specifications.
The dual-function role of the H6054 across both high beam and low beam positions in the 1986-1993 model years indicates the W350 used a two-headlamp system during that period, where a single sealed beam unit per side handles both beam modes through separate filaments.
