Chevrolet Two-Ten Series headlight bulbs utilize H6024 and H6006 size specifications for both high and low beam applications. The replacement chart covers vehicle production years spanning 1953 to 1957.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Two-Ten Series uses two sealed beam unit types across its model years: the H6024 and the H6006. Both conform to ANSI standards recognized in the United States and Canada and operate on a 12-volt electrical system.
The H6024 is a 7-inch round sealed beam unit. Because it is a sealed beam design, the entire unit is replaced rather than an internal filament or bulb element.
The H6006 is a 5x7-inch rectangular sealed beam unit and shares the same sealed beam construction as the H6024, requiring full unit replacement when the light fails.
The 1955-1957 Chevrolet Two-Ten Series uses the H6024 for both high beam and low beam headlight positions. A single unit type serves both functions across those years.
The 1953-1954 Two-Ten Series uses the H6006 for both high beam and low beam positions, reflecting a rectangular sealed beam format rather than the round format adopted in later years.
The H6024 and H6006 are not interchangeable. Their physical formats differ in shape and size, making cross-substitution between the two unit types incompatible regardless of shared voltage rating.
The shift from H6006 to H6024 occurred between the 1954 and 1955 model years, representing a change from a rectangular to a round sealed beam format across the Two-Ten Series headlight system.
