Dodge Sierra high beam and low beam headlight bulb sizes include H5001, H6024, and H6006 options, with replacement specifications varying by bulb size across different production configurations. The replacement chart covers 1954 through 1959 model years with corresponding headlight bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
All headlight bulb sizes listed for the Dodge Sierra across the 1954-1959 model years are sealed beam units conforming to ANSI standards recognized in both the United States and Canada. Each operates on a 12V electrical system.
Sealed beam units are self-contained assemblies in which the filament, reflector, and lens are fused into a single glass envelope. When a sealed beam fails, the entire unit requires replacement rather than an internal bulb.
The H6006, a 5x7-inch rectangular sealed beam, appears in both the high beam and low beam positions for the 1954-1955 model years, meaning a single bulb type serves both functions on those vehicles.
From 1957-1959, the Dodge Sierra uses separate bulb types for each beam function: the H5001, a 4-inch square sealed beam, handles the high beam, while the H5006, a 5.75-inch round sealed beam, handles the low beam.
The 1956 Dodge Sierra uses the H6024, a 7-inch round sealed beam, for both the high beam and low beam positions, making it the only model year in these specifications to use that particular unit.
The physical form factor differs across the listed bulb types, ranging from 4-inch square (H5001) and 5.75-inch round (H5006) to 5x7-inch rectangular (H6006) and 7-inch round (H6024). These differing shapes and sizes mean the units are not interchangeable with one another.
Because each sealed beam format is physically distinct, substituting one type for another is not possible without modification to the headlight housing, as the mounting and lens geometry are specific to each unit.
The ANSI standardization of all four bulb types means equivalent units from different manufacturers share the same electrical and physical specifications, provided the correct ANSI designation is matched.
