The Pontiac Ventura headlight bulb specifications include H6024 and H5001 sizes for high beam applications, along with H6024 and H5006 sizes for low beam functions. The replacement chart covers vehicle production years spanning 1960 to 1977 with corresponding bulb size data.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H6024 is a 7-inch round sealed beam unit operating at 12V and conforming to ANSI standards for the US and Canadian markets. It functions as both the high beam and low beam headlight across the Pontiac Ventura model years 1971-1977, meaning a single bulb type serves dual beam positions in those years.
Sealed beam units such as the H6024, H5001, and H5006 are self-contained assemblies in which the filament, reflector, and lens are fused into one unit. When the filament fails, the entire assembly requires replacement rather than an internal bulb swap.
The 1960-1961 Pontiac Ventura uses different sealed beam types for high and low beam positions. The H5001, a 4-inch square sealed beam unit at 12V, serves the high beam, while the H5006, a 5.75-inch round sealed beam unit also at 12V, serves the low beam.
Because the high and low beam positions on the 1960-1961 Ventura use physically distinct sealed beam units of different shapes and sizes, the H5001 and H5006 are not interchangeable with each other despite both conforming to ANSI standards.
The H6024 used in the 1971-1977 Ventura is not interchangeable with the H5001 or H5006 used in the 1960-1961 Ventura, as the units differ in physical form factor and designated beam function.
All three sealed beam types referenced in these specifications, the H6024, H5001, and H5006, operate at 12V and carry ANSI standardization applicable to both the United States and Canada.
