Plymouth Valiant headlight bulbs utilized H6024 and H5001 sizes for high beam applications, along with H6024 and H5006 sizes for low beam functions, with each bulb size corresponding to specific lighting requirements. The replacement chart documents bulb size specifications across vehicle production years spanning 1960 to 1976.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Plymouth Valiant uses two distinct headlight configurations across its production run. The 1960-1962 model years use a four-headlight system with separate high and low beam sealed beam units, while the 1963-1976 model years use a two-headlight system in which a single H6024 unit handles both high and low beam functions.
The H6024 is a 7-inch round sealed beam unit rated at 12V and built to ANSI standards for the US and Canadian markets. It serves as both the high beam and low beam headlight on the Plymouth Valiant from 1963-1976.
The H5001 is a 4-inch square sealed beam unit rated at 12V and conforming to ANSI standards. It functions as the high beam headlight on the 1960-1962 Valiant.
The H5006 is a 5.75-inch round sealed beam unit rated at 12V and built to the same ANSI standard. It serves as the low beam headlight on the 1960-1962 Valiant, pairing with the H5001 in a dual-unit system.
All three bulb types, H6024, H5001, and H5006, are sealed beam units. In each case, the entire unit is replaced rather than an internal filament or bulb element.
The H5001 and H5006 are not interchangeable with each other or with the H6024. Each carries a distinct physical form factor, with the H5001 being square and the H5006 and H6024 being round units of different sizes, making cross-substitution incompatible.
The shift from the dual-unit H5001 and H5006 pairing to the single H6024 unit occurred between the 1962 and 1963 model years, reflecting a change in the headlight system design for the Valiant.
