The Dodge B150 headlight bulb uses 9004, H6054, or H6024 sizes for both high and low beam applications. A replacement chart covering 1981 to 1994 contains vehicle production years and 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 Dodge B150 uses sealed beam headlight units across most of its model range, with the 9004 halogen bulb being the sole exception, appearing only in the 1994 model year for both high and low beam positions.
The 9004 is a dual-filament halogen bulb with a P29t base, rated at 12V and operating at 65W on high beam and 45W on low beam. Its dual-filament design allows a single bulb to serve both beam functions within one housing.
Sealed beam units such as the H6054, H6024, H4651, H4656, and H4652 are not serviceable at the bulb level. When a sealed beam fails, the entire unit requires replacement, as the lens, reflector, and filament are fused into a single assembly.
The H6054, a 5x7-inch rectangular sealed beam, was used on the Dodge B150 from 1988-1993 for both high and low beam positions, making it the most consistently specified unit across the model's history in these specifications.
For the 1984-1987 model years, the correct sealed beam type depended on whether the vehicle was equipped with a two-headlamp or four-headlamp system. Two-headlamp configurations used the H6024, a 7-inch round sealed beam, while four-headlamp configurations required separate high and low beam units.
In four-headlamp configurations from 1984-1987, the high beam position used the H4651 and the low beam position used the H4656. Both are 4x6-inch rectangular sealed beam units, and though similar in form, they are distinct part numbers and are not interchangeable between positions.
The H4652, used for both beam positions in 1981-1983, is a variant of the H4651 in a 4x6-inch rectangular sealed beam format. Despite the physical similarity, substituting one for the other without confirming the correct specification risks incorrect beam output.
All sealed beam types listed across the B150 specifications conform to ANSI standards applicable in the United States and Canada and operate on a 12V electrical system.
