The Jeep FC150 high beam and low beam headlight bulb size specifications include H6024 and H6006 bulb options for this vehicle model. The replacement chart covers 1957 to 1966 production years 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 Jeep FC150 uses two distinct sealed beam headlight units across its listed model years: the H6024 in 1966 and the H6006 in 1957.
The H6024 is a 7-inch round sealed beam unit operating at 12V, conforming to ANSI standards applicable in both the United States and Canada.
The H6006 is a 5x7-inch rectangular sealed beam unit, also rated at 12V and built to the same ANSI standard coverage as the H6024.
Both the H6024 and H6006 are sealed beam units, meaning the lens, reflector, and filament are fused into a single assembly. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The H6024 and H6006 are not interchangeable. The round and rectangular form factors are physically incompatible, and substituting one for the other is not supported by the specifications.
The 1966 FC150 uses the H6024 for both high beam and low beam functions, meaning a single sealed beam type serves both lighting modes on that model year.
The 1957 FC150 similarly uses the H6006 for both high beam and low beam positions, following the same dual-function sealed beam arrangement as the 1966 configuration.
