The Dodge B-3 high beam and low beam headlight bulbs both utilize the H6006 size. The replacement chart covers 1951 to 1952 vehicle production years 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 H6006 is the sole bulb type listed across all headlight positions for the Dodge B-3, covering both the 1951-1952 model years.
The H6006 is an ANSI-standard sealed beam unit recognized in both the United States and Canada. It follows a 5x7-inch rectangular form factor and operates at 12 volts.
As a sealed beam unit, the H6006 does not contain a separately replaceable filament or bulb element. When the unit fails, the entire assembly is replaced as one piece.
The H6006 serves both the high beam and low beam headlight positions on the Dodge B-3 for 1951-1952, meaning a single bulb type covers all forward lighting functions.
The sealed beam design of the H6006 integrates the reflector, lens, and filament into one fixed unit, which was the prevailing headlight construction standard of that era.
Because the same H6006 specification applies to both beam positions, the physical unit used for high beam and low beam fitment is identical, though the internal filament configuration determines the beam function.
