The Dodge C-3 headlight bulb specifications include H6024 and H6006 sizes for both high and low beam applications, with bulb compatibility data presented across multiple configurations. The replacement chart covers 1954 through 1956 model years and documents headlight bulb size requirements for vehicles produced during that production period.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6006 sealed beam unit is a 5x7-inch rectangular format operating at 12 volts, conforming to ANSI standards recognized in both the United States and Canada. The entire unit is replaced when the light fails, as the bulb is not a separate serviceable component.
The H6024 sealed beam unit is a 7-inch round format, also rated at 12 volts and built to the same ANSI standard. Like the H6006, it is a sealed assembly requiring full unit replacement rather than individual bulb replacement.
The Dodge C-3 used the H6006 rectangular sealed beam for both high and low beam headlights in 1954-1955, meaning a single bulb type served the full headlight system across those two years.
For the 1956 model year, both the high beam and low beam positions transitioned to the H6024 round sealed beam, representing a change in headlight format from the rectangular units used previously.
Because the H6006 and H6024 differ in both shape and physical size, the two units are not interchangeable. The rectangular 5x7-inch H6006 and the round 7-inch H6024 each require housings designed specifically for their respective formats.
