Ford E-300 high beam and low beam headlight bulbs both utilize the H6024 bulb size. The replacement chart covers vehicle production spanning 1969 to 1974.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Ford E-300 uses the H6024 bulb size for both high beam and low beam headlights across the 1969-1974 model years.
The H6024 is an ANSI-standardized sealed beam unit, meaning the lens, reflector, and filament are fused into a single non-serviceable assembly. When the filament fails, the entire unit is replaced rather than an individual bulb.
The H6024 unit is a 7-inch round sealed beam operating at 12 volts, a format that was widely standardized across North American vehicles during this era.
Because the H6024 serves both the high beam and low beam positions on the Ford E-300, the same unit type is used across all four headlight sockets where a dual-headlight configuration is present.
The ANSI standardization of the H6024 means units produced by different manufacturers share the same physical form factor and electrical ratings, allowing interchangeability between compliant products.
