Additional Notes

The Dodge B350 uses sealed beam headlight units across most of its model range, covering the 1981-1993 model years. Sealed beam units are self-contained glass assemblies in which the filament, reflector, and lens are fused together as a single unit. When a sealed beam fails, the entire assembly is replaced rather than an individual bulb.
The 9004 bulb, used in the 1994 model year for both high and low beam functions, differs fundamentally from the sealed beam units used in prior years. It is a dual-filament halogen bulb with a P29t base, rated at 12V with 65W on high beam and 45W on low beam. A single 9004 unit serves both beam functions through its two filaments.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V. It appears on the Dodge B350 for both high and low beam positions across the 1988-1993 model years, making it the most frequently specified sealed beam type in these specifications.
The H6024 is a 7-inch round sealed beam unit operating at 12V. It is specified for the 1984-1987 model years exclusively on configurations equipped with two headlamps, covering both high and low beam positions within those years.
The 4x6-inch rectangular sealed beam format is represented by three distinct types: H4651, H4656, and H4652. All three operate at 12V and share the same physical format, though they are separate ANSI-designated units. H4651 covers high beam positions, while H4656 and H4652 cover low beam positions across various years.
For the 1984-1987 model years, the Dodge B350 with four headlamps uses a different bulb type than the two-headlamp configuration. The four-lamp setup uses 4x6-inch rectangular sealed beam units, while the two-lamp setup uses the 7-inch round H6024 unit. These configurations are not interchangeable.
The low beam position on four-headlamp B350 vehicles shows variation across years. The H4656 is specified for 1982, 1984, 1986, and 1987, while the H4652 is specified for 1981, 1983, and 1985. Although both are 4x6-inch rectangular sealed beam units, they carry distinct ANSI designations and are not listed as interchangeable within these specifications.
All bulb and sealed beam types listed across the full model range are ANSI-standard units approved for use in the United States and Canada, and all operate on a 12V electrical system.
