Additional Notes

The Mazda B2000 headlight specifications cover the 1979-1987 model years, with two distinct sealed beam configurations used across that span depending on the year.
The H6054 is a 5x7-inch rectangular sealed beam unit operating at 12V and conforming to ANSI standards applicable in the US and Canada. It serves as both the high beam and low beam headlight on the B2000 for the 1982-1987 model years, with the exception of 1985, which is absent from the specifications.
Sealed beam units such as the H6054, H5001, and H5006 do not contain a replaceable bulb element. When a unit fails, the entire assembly is replaced as a single component.
For the 1979-1981 model years, the B2000 uses separate sealed beam types for high and low beam functions. The H5001, a 4-inch square unit, handles the high beam, while the H5006, a 5.75-inch round unit, handles the low beam.
The H5001 and H5006 are not interchangeable with each other despite both being ANSI-standard 12V sealed beam units, as they differ in physical shape and assigned beam function.
The shift from the H5001/H5006 pairing to the H6054 rectangular unit between the 1981 and 1982 model years means that headlight assemblies from these two periods are not cross-compatible.
All three sealed beam types in these specifications, H6054, H5001, and H5006, operate on a 12V electrical system and comply with ANSI standards recognized in both the US and Canada.
