Nissan 710 headlight bulbs utilize H5001 size for high beam and H5006 size for low beam applications. The replacement chart covers 1974 through 1977 production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 710 uses two sealed beam headlight types across all documented model years: H5001 for high beam and H5006 for low beam, both applying uniformly to the 1974-1977 range.
Both the H5001 and H5006 are ANSI-standardized sealed beam units rated at 12V, conforming to specifications recognized in the United States and Canada.
The H5001 is a 4-inch square sealed beam unit, while the H5006 is a 5.75-inch round sealed beam unit. These two types are physically distinct and are not interchangeable with one another.
Sealed beam construction means the lens, reflector, and filament are fused into a single glass housing. When the filament fails, the entire unit requires replacement rather than an internal bulb swap.
The square profile of the H5001 and the round profile of the H5006 reflect a common dual-headlight configuration of the era, where separate housings handled dedicated high and low beam functions independently.
Because both bulb types follow ANSI standards, equivalent sealed beam units from other manufacturers conforming to the same H5001 or H5006 specifications are generally considered compatible replacements, provided the physical form and voltage rating match.
