The Dodge 330 uses H6024 and H5001 bulbs for high beam headlights and H6024 and H5006 bulbs for low beam headlights, with bulb size specifications varying by application. The replacement chart covers 1963 to 1964 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.
The Dodge 330 uses sealed beam headlight units across both model years in the specifications, meaning the lens, reflector, and filament are fused into a single assembly that is replaced as a whole rather than accepting a separate replaceable bulb.
All three sealed beam types listed for the Dodge 330 conform to ANSI standards recognized in both the United States and Canada, and all operate on a 12-volt electrical system.
The H6024 is a 7-inch round sealed beam unit used for both the high beam and low beam positions in the 1964 model year, meaning a single bulb type serves the entire headlight system that year.
The 1963 model year uses two distinct sealed beam types: the H5001, a 4-inch square unit, handles the high beam function, while the H5006, a 5.75-inch round unit, handles the low beam function.
Because the 1963 high beam (H5001) is square and the 1963 low beam (H5006) is round, the two units are physically incompatible with each other's housings and are not interchangeable.
The transition from 1963 to 1964 represents a change in headlight architecture, with the 1964 system consolidating to a single H6024 type for both beam functions rather than using separate units for each.
The H6024 and H5006 are both round sealed beam units but differ in size, making them non-interchangeable despite sharing the same general form factor.
